    There has been a longstanding debate about the roles of surgical bypass graft, percutaneous transluminal angioplasty, subintimal angioplasty, and conservative management for femoro-popliteal occlusive disease. Subintimal angioplasty was first described in 1987 as a method of performing an endovascular arterial bypass. The subintimal space at the start of the occlusion is entered with a catheter and a wire loop is used to cross the occlusion and reenter the vessel lumen distally. In patients with critical limb ischemia, there is high quality evidence demonstrating that the limb salvage rate and amputation-free survival rates for surgery and endovascular treatment are similar, but surgery is more expensive than angioplasty in the short term. In patients with intermittent claudication, surgical bypass using an autologous saphenous vein graft is currently believed to be the gold standard, but this is increasingly questioned in the light of recent advances in endovascular techniques. Surgical bypass with vein graft offers a 2-year patency of 81%, compared with 67% for a polytetrafluoroethylene (PTFE) graft and at best 67% for subintimal angioplasty. The better patency offered by surgery must be balanced against a higher morbidity and mortality. To conclude, subintimal angioplasty is an extremely valuable technique in the management of critical limb ischemia. Based on the evidence to date, this technique is likely to have an increasing role in the management of intermittent claudication over the coming years, particularly if the risk of general anaesthesia is high or there is no suitable vein.

    Objective. To review our preliminary experience and evaluate our early results of a combined intraoperative iliac angioplasty and stenting with infrainguinal revascularization in multilevel atherosclerotic occlusive disease.``Methods. From July 1999 to April 2000, intraoperative iliac angioplasty and stenting combined with simultaneous femoro-popliteal bypass were performed on 12 lower extremities of 10 patients suffering from multilevel atherosclerotic occlusive disease. There were 8 men and 2 women, average 72 years. The indications for procedures included disabling claudication in 3 and rest pain in 7 patients.``Results. Eleven iliac angioplasty and stent procedures combined with simultaneous 9 femoro-popliteal bypass and 3 femoro-femoral-popliteal bypass were performed in 12 limbs of 10 patients. Angioplasty and stent placement was technically successful in all patients. One contralateral femoral-popliteal bypass was failure after femorofemoral-popliteal bypass. There were no additional instances of procedural or postoperative morbidity or mortality. Mean follow-up was 5 months (range 1 ~ 10 months). During the follow-up period, one femoro-infrapoplitealgraft became occluded after 7 months and above-knee amputation was required. The cumulative primary patency rate of stented iliac arteries, femoro-femoral bypass grafts and femoro-popliteal bypass grafts were 100% ( 11 /11), 100% (3/3) and 90. 9% (10/11) in the follow-up period, respectively. The amputation rate was 8.3%(1/12).``Conclusions. Intraoperative iliac artery PTA and stent placement can be safely and effectively performed simultaneously with infrainguinal revascularization for multilevel atherosclerotic occlusive disease by skilled vascular surgeon, using a prtable C arm fluoroscopy in the operating room. Furthermore, iliac artery PTA and stenting was valuable adjunct to distal bypass either to improve inflow and outflow, or to reduce the extent of traditional surgical intervention, and also, any

    Objectives: Cost-effectiveness analysis of three diagnostic imaging strategies for the assessment of aortoiliac and femoropopliteal arteries in patients with peripheral arterial occlusive disease. The strategies were: angiography as the reference strategy, duplex scanning (DS) plus supplementary angiography (S1) and DS plus confirmative angiography (S2). Design, materials and methods: A decision model was built with sensitivity and specificity data from literature, supplemented with prospective hospital cost data in Euro ( Euro ). The probability of correctly identifying the status of a lesion was taken as the primary outcome. We compared strategies by assessing the extra costs per additional correctly identified case. Results: Assuming no false positive or false negative results, angiography is the most effective strategy if the prevalence of significant obstructive lesions in the aortoiliac and femoropopliteal tract exceeds 70%, or if the sensitivity of duplex scanning is lower than 83%. In case of lower prevalence, strategy S1 becomes equally or even more effective than angiography. At a prevalence of 75%, performing angiography costs Euro 8443 per extra correctly identified case compared with strategy S1. Conclusions: In most situations angiography is more effective than diagnostic strategy S1. However, if society is unwilling to pay more than Euro 8443 for knowing a patient's disease status, diagnostic strategy S1 is a cost-effective alternative to angiography, especially at lower prevalence values.

    Full Text Available Kalkidan Bishu,1,2 Ehrin J Armstrong1,21Division of Cardiology, University of Colorado, Aurora, 2Denver VA Medical Center, Denver, CO, USAAbstract: Femoropopliteal lesions account for a significant proportion of endovascular interventions for peripheral artery disease in patients with disabling claudication or chronic limb ischemia. The femoropopliteal artery crosses two joint structures (hip and knee joints and courses through the muscular adductor canal in the thigh, which places the artery at increased biomechanical stress. There is a critical need for stent platforms with a reduced risk of stent fracture while maintaining patency during long-term follow-up. The Supera peripheral stent system has a braided nickel–titanium alloy stent designed to withstand the unique stressors along the course of the femoropopliteal artery. This design may be associated with improved patency in association with reduced stent fracture rates on short- and medium-term follow-up. Further studies, including randomized controlled studies, comparing the Supera interwoven nickel–titanium alloy stent system with other stent platforms and angioplasty alone are needed.Keywords: peripheral artery disease, femoropopliteal atherosclerosis, SUPERA interwoven nitinol stent, stent fracture

    To analyze the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO{sub 2} as primary contrast in patients with no formal contraindication to iodine, aiming to decrease allergic reactions and potential nephrotoxicity in high-risk patients. We describe the results of ten angioplasties of TASC C and D femoropopliteal lesions using CO{sub 2} as primary contrast in patients with high risk for open revascularization and no formal contraindication to iodine. We analyzed feasibility of the procedures, complications, quality of the angiographic images, clinical and surgical outcomes, and costs of C and D lesions treated using CO{sub 2} as contrast medium. The use of CO{sub 2} in C and D lesions needed iodine complementation in most of the cases (nine cases) but decreased the potential nephrotoxicity of iodine contrast medium by the reduction of its volume in this group of high-risk patients. The extension of the arterial lesions was the factor that most contributed to the need for iodine supplementation due to the difficulty to visualize the refill after a long arterial occlusion. The use of CO{sub 2} as contrast in patients with C and D lesions with no restriction for iodine contrast medium was an alternative that did not dismiss the need of iodine supplementation in most of the cases, but could decrease the potential nephrotoxicity of iodine constrast medium.

    PurposeThe purpose of the study was to assess the safety and midterm effectiveness of endovascular treatment in Trans-Atlantic Inter-Society Consensus II (TASC-II) D femoropopliteal occlusions in patients with critical limb ischemia (CLI).MethodsPatients with CLI who underwent endovascular treatment for TASC-D de novo femoropopliteal occlusive disease between September 2008 and December 2013 were selected. Data included anatomic features, pre- and postprocedure ankle-brachial index, duplex ultrasound, and periprocedural complications. Sustained clinical improvement, limb salvage rate, freedom from target lesion revascularization (TLR), and freedom from target extremity revascularization (TER) were assessed by Kaplan–Meier estimation and predictors of restenosis/occlusion with Cox analysis.ResultsThirty-two patients underwent treatment of 35 TASC-D occlusions. Mean age was 76 ± 9. Mean lesion length was 23 ± 5 cm. Twenty-eight limbs (80 %) presented tissue loss. Seventeen limbs underwent treatment by stent, 13 by stent-graft, and 5 by angioplasty. Mean follow-up was 29 ± 20 months. Seven patients required major amputation and six patients died during follow-up. Eighteen endovascular and three surgical TLR procedures were performed due to restenosis or occlusion. Estimated freedom from TLR and TER rates at 2 years were 41 and 76 %, whereas estimated primary and secondary patency rates were 41 and 79 %, respectively.ConclusionsEndovascular treatment for TASC II D lesions is safe and offers satisfying outcomes. This patient subset would benefit from a minimally invasive approach. Follow-up is advisable due to a high rate of restenosis. Further follow-up is necessary to know the long-term efficacy of these procedures.

    To perform a cost-effectiveness analysis to help hospital decision-makers with regard to the use of drug-coated balloons compared with bare metal stents and uncoated balloons for femoropopliteal occlusive disease. Clinical outcomes were extracted from the results of meta-analyses already published, and cost units are those used in the Quebec healthcare network. The literature review was limited to the last four years to obtain the most recent data. The cost-effectiveness analysis was based on a 2-year perspective, and risk factors of reintervention were considered. The cost-effectiveness analysis indicated that drug-coated balloons were generally more efficient than bare metal stents, particularly for patients with higher risk of reintervention (up to CAD$1686 per patient TASC II C or D). Compared with uncoated balloons, results indicated that drug-coated balloons were more efficient if the reintervention rate associated with uncoated balloons is very high and for patients with higher risk of reintervention (up to CAD$3301 per patient). The higher a patient's risk of reintervention, the higher the savings associated with the use of a drug-coated balloon will be. For patients at lower risk, the uncoated balloon strategy is still recommended as a first choice for endovascular intervention.

    The clinical outcomes of nitinol stents for femoropopliteal arterial (FP) disease in patients on hemodialysis were assessed. Endovascular therapy (EVT) is accepted for symptomatic FP disease. However, the clinical outcomes of patients on dialysis are not well known. A multicenter retrospective study was conducted with data between November 2010 and August 2013. A total of 484 consecutive patients who successfully underwent EVT for FP disease with nitinol stents were recruited and analyzed. Patients were categorized into the hemodialysis group (N = 161) and non-hemodialysis group (N = 323). The primary measure was primary patency verified by duplex ultrasound at a rest peak systolic velocity (PSVR) of >2.5, and secondary measures were freedom from target lesion revascularization (TLR) and major amputation-free survival (AFS). Average follow-up duration was 19.5 ± 13.5 months. The primary patency rate at 3 years was significantly lower in the hemodialysis group than the non-hemodialysis group (33.8 vs. 43.7 %; p = 0.036). Freedom from TLR at 3 years was 55.0 % in the hemodialysis group and 66.1 % in the non-hemodialysis group (p = 0.032). The hemodialysis group showed a significantly lower AFS rate at 3 years than the non-hemodialysis group (86.4 vs. 58.2 %; p nitinol stent use resulted in a lower patency rate, higher TLR rate, and lower AFS rate compared to non-hemodialysis patients. These data suggest that nitinol stent implantation for FP arteries in hemodialysis patient needs to be reconsidered.

    Full Text Available Objective: Nitinol stenting could bring the better outcome in endovascular therapy for femoropopliteal disease. However, it might be expected that recent marked advances in both device technology and operator technique had led to improved efficacy of balloon angioplasty even in this segment. The aims of this study were to evaluate the clinical impact of balloon angioplasty for femoropopliteal disease and make risk stratification clear by propensity score matching analysis. Methods: Based on the multicenter retrospective data, 2758 patients (balloon angioplasty: 729 patients and nitinol stenting: 2029 patients, those who underwent endovascular therapy for femoropopliteal disease, were analyzed. Results: The propensity score matching procedure extracted a total of 572 cases per group, and the primary patency rate of balloon angioplasty and nitinol stenting groups after matching was significantly the same (77.2% vs 82.7% at 1 year; 62.2% vs 64.3% at 3 years; 47.8% vs 54.3% at 5 years. In multivariate Cox hazard regression analysis, significant predictors for primary patency were diabetes mellitus, regular dialysis, cilostazol use, chronic total occlusion, and intra-vascular ultra-sonography use. The strategy of balloon angioplasty was not evaluated as a significant predictor for the primary patency. After risk stratification using five items (diabetes mellitus, regular dialysis, no use of intra-vascular ultra-sonography, chronic total occlusion, and no use of cilostazol: the DDICC score, the estimated primary patency rates of each group (low, DDICC score 0–2; moderate, DDICC score 3; high risk, DDICC score 4–5 were 88.6%, 78.3%, and 63.5% at 1 year; 75.2%, 60.7%, and 39.8% at 3 years; and 66.0%, 47.1%, and 26.3% at 5 years (p < 0.0001. The primary patency rate of balloon angioplasty and nitinol stenting groups was significantly the same in each risk stratification. Conclusion: This study suggests that balloon angioplasty does

    The Zilver PTX drug-eluting stent (Cook Ireland Ltd., Limerick, Ireland) represents an advance in endovascular treatments for atherosclerotic superficial femoral artery (SFA) disease. Clinical data demonstrate improved clinical outcomes compared to bare-metal stents (BMS). This analysis assessed the likely impact on the French public health care budget of introducing reimbursement for the Zilver PTX stent. A model was developed in Microsoft Excel to estimate the impact of a progressive transition from BMS to Zilver PTX over a 5-year horizon. The number of patients undergoing SFA stenting was estimated on the basis of hospital episode data. The analysis from the payer perspective used French reimbursement tariffs. Target lesion revascularization (TLR) after primary stent placement was the primary outcome. TLR rates were based on 2-year data from the Zilver PTX single-arm study (6 and 9 %) and BMS rates reported in the literature (average 16 and 22 %) and extrapolated to 5 years. Net budget impact was expressed as the difference in total costs (primary stenting and reinterventions) for a scenario where BMS is progressively replaced by Zilver PTX compared to a scenario of BMS only. The model estimated a net cumulative 5-year budget reduction of Euro-Sign 6,807,202 for a projected population of 82,316 patients (21,361 receiving Zilver PTX). Base case results were confirmed in sensitivity analyses. Adoption of Zilver PTX could lead to important savings for the French public health care payer. Despite higher initial reimbursement for the Zilver PTX stent, fewer expected SFA reinterventions after the primary stenting procedure result in net savings.

Risk stratification was based on FeDCLIP (female, diabetes, dialysis, CLI, lesion length >150 mm and poor runoff score. The DCB outcomes among the different risk groups were compared and factors predicting restenosis were analyzed during follow-up.Most of study participants (84% were moderate to high-risk patients. The procedural success rate was 100% and the 30-day major adverse vascular event rate was 2.1%. The mean lesion length was 178 ± 106 mm and the mean follow-up time was 428 ± 145 (range 50-782 days. The binary restenosis-free and clinically driven target lesion revascularization (CD-TLR-free rates at 12 months were 77.5% and 84.3%, respectively, for all participants. No significant differences were observed in 1-year binary restenosis and CD-TLR rates in the low-, moderate-, and high-risk groups (60%, 84%, and 73%: p = 0.396; 78%, 89%, and 80%: p = 0.635, respectively.

The DCB procedure holds promise to improve vessel patency; however, lesion length >150 mm and major tissue loss were independent predictors for binary restenosis after the treatment.

    Curved planar reformation allows comprehensive visualization of arterial flow channels, providing information about calcified and noncalcified plaques and degrees of stenoses. Existing semiautomated centerline-extraction algorithms for curved planar reformation generation fail in severely diseased and occluded arteries. We explored whether contralateral shape information could be used to reconstruct centerlines through femoropopliteal occlusions. We obtained CT angiography data sets of 29 subjects (16m/13f, 19-86yo) without peripheral arterial occlusive disease and five consecutive subjects (1m/4f, 54-85yo) with unilateral femoropopliteal arterial occlusions. A gradient-based method was used to extract the femoropopliteal centerlines in nondiseased segments. Centerlines of the five occluded segments were manually determined by four experts, two times each. We interpolated missing centerlines in 2475 simulated occlusions of various occlusion lengths in nondiseased subjects. We used different curve registration methods (reflection, similarity, affine, and global polynomial) to align the nonoccluded segments, matched the end points of the occluded segments to the corresponding patent end points, and recorded maximum Euclidean distances to the known centerlines. We also compared our algorithm to an existing knowledge-based PCA interpolation algorithm using the nondiseased subjects. In the five subjects with real femoropopliteal occlusions, we measured the maximum Euclidean distance and the percentage of the interpolation that remained within a typical 3 mm radius vessel. In the nondiseased subjects, we found that the rigid registration methods were not significantly (pinterpolation of centerlines through arterial occlusions.

    In the last few years the treatment of superficial femoral artery (SFA) occlusive disease has undergone greater changes in management including more aggressive endoluminal therapy, especially in the elderly patients who are at high risk for extra-vascular comorbidities from the surgical approach. While acute and chronic arterial limb ischemia is the conditions which the interventional cardiologists frequently encounter, the elderly population represents special problematic clinical and anatomical setting due to heavy calcification and poor distal run-off. Arterial thrombolysis, rheolytic thrombectomy, mechanical thrombectomy, laser angioplasty, cryoplasty, and new flexible long stents are some of the promising techniques to improve the technical and clinical outcomes in these elderly patients.

    Background:Sarpogrelate is a selective 5-hydroxytryptamine (5-HT) receptor subtype 2A antagonist which blocks 5-HT induced platelet aggregation and proliferation of vascular smooth muscle cells.We compared the efficacy of sarpogrelate-based dual antiplatelet therapies for the prevention of restenosis and target lesion revascularization (TLR) rates comparing with that of clopidogrel after percutaneous endovascular interventions (EVIs) of femoropopliteal (FP) arterial lesions.Methods:This prospective,multicenter,randomized clinical trial recruited a total of 120 patients with successful EVI of FP lesions at seven centers across China between January 2011 and June 2012.Patients were randomized to receive either sarpogrelate (1 00 mg trice daily for 6 months,n =63) or clopidogrel (75 mg once daily for 6 months,n =57).All patients also received oral aspirin (100 mg once daily for 12 months).Clinical follow-up was conducted up to 12 months postprocedure.Results:There was no significant difference between the two groups in basic demographic data.The restenosis rate was higher in the clopidogrel group (22.80%) than in sarpogrelate group (17.50%),but there was no significant difference between these two groups (P =0.465).The TLR rate,ipsilateral amputation rate,mortality in all-cause and bleeding rate were also similar in the two groups (P > 0.05).Conclusions:Aspirin plus sarpogrelate is a comparable antithrombotic regimen to aspirin plus clopidogrel after EVI of FP arterial lesions.Dual antiplatelet therapies might play an important role in preventing restenosis after successful EVI of FP lesions.

    Full Text Available Background. To compare the clinical outcomes between excimer laser-assisted angioplasty (ELA with spot stent (group A and primary stenting (group B in intermediate to long femoropopliteal disease. Methods. Outcomes of 105 patients totaling 119 legs treated with two different strategies were analyzed retrospectively in a prospectively maintained database. Results. Baseline characteristics were similar in both groups. Better angiographic results and lesser increase of serum C-reactive protein levels (0.60 ± 0.72 versus 2.98 ± 0.97 mg/dL, P<0.001 after the intervention were obtained in Group B. Group A had inferior 1-year outcomes due to higher rate of binary restenosis (67% versus 32%, P=0.001 and lower rate of primary patency (40% versus 58%, P=0.039. Rates of amputation-free survival, target vessel revascularization, assisted primary patency, and stent fracture at 24 months were similar in both groups (80% versus 82%, P=0.979, 65% versus 45%, P=0.11, 78% versus 80%, P=0.75 and 6.3% versus 6.8%, P=0.71, resp.. Conclusion. Greater vascular inflammation after ELA with spot stent resulted in earlier restenosis and inferior 1-year clinical outcomes than primary stenting. This benefit was lost in the primary stenting group at 2 years due to late catch-up restenosis. Active surveillance with prompt intervention was required to maintain the vessel patency.

    .BACKGROUND: Endovascular treatment of peripheral arterial disease (PAD presents low morbidity and mortality rates; however, mid and long-term patency rates remain controversial. Cryoplasty was developed as an attempt to resolve the main problems related to angioplasty: dissection, recoil and restenosis. OBJECTIVE: To evaluate clinical results and mid-term patency in patients treated with cryoplasty of femoropopliteal arterial disease. METHODS: Patients with indication for endovascular lower limb revascularization according to Fontaine and Rutherford clinical classifications and to TASC II anatomical classification underwent cryoplasty using the PolarCath® peripheral dilatation balloon catheter. Clinical results and anatomical patency were analyzed by duplex ultrasound scan at follow-up, RESULTS: Ten patients with femoropopliteal arterial disease were treated with cryoplasty. Nine patients presented with intermittent claudication and one patient had an ischemic ulcer. Three patients had class B lesions and seven patients had class A lesions according to the TASC II. Initial technical success was achieved in all patients, and one patient needed stenting during the procedure due to dissection. One patient died due to complications in the postoperative period. Nine patients were followed up for 31.6 months on average (18-35, with primary patency rate of 77.7% and secondary patency rate of 100%. All patients were asymptomatic at the end of this period (Fontaine stage I. CONCLUSIONS: Cryoplasty is a safe technique for the treatment of femoropopliteal arterial disease that presents low morbidity rates, short-term and mid-term results comparable to conventional angioplasty, as well as potential advantages of lower dissection, recoil and mid-term restenosis rates.

    Full Text Available Introduction/Aim. Occlusive disease of lower limb arteries have been so far traditionally best treated with bypass surgery, but we want to find minimally invasive approach that should be at least as good as conventional surgery, and hopefully better. The aim of this study was to evaluate SMART Control stents (Cordis, J&J in Trans Atlantic Society Consensus (TASC B and C femoropopliteal lesions during one-year follow-up. Methods. Retrospective nonrandomized analysis included forty arteries in consecutive 40 patients who were stented with SMART Control stents. Primary patency at 12-month verified with Duplex Ultrasound and Acute Brachial Index (ABI as well as freedom from Target Vessel Revascularization (TVR were primary endpoints. Results. Primary technical success at stent implantation was 100%. Mean ABI values were preprocedurally 0.50, postprocedurally 0.83, at one month 0.86, at six months 0.84, at one year 0.78. After one year 39 stents were patent (97.5%. Conclusion. Excellent performance of the stent from technical point of view and a midterm results in vessel patency, as well as the absence of need for TVR were achieved. Yet, life expectancy in this cohort group of patients demands longer follow up data to draw a definite sustained positive conclusion.

    Backround. Intermittent claudication is a classic symptom of peripheral arterial disease. It is mainly treated conservatively but if this fails, a form of revascularization is indicated. The revascularization in chronic occlusion of femoropopliteal region is currently performed by two basic methods: the standard method of surgical bypass and the newer miniinvasive alternative represented by the endovascular method. The treatment of patients with solely claudication and long occlusion of femoropopliteal region remains controversial. The aim of this minireview was to determine whether surgical bypass is still the best method of choice in a time of endovascular techniques. A MEDLINE search for original and review articles using key terms, intermittent claudication and long femoropopliteal oclusion. No ideal treatment for long occlusions of the femoropopliteal segment has been established to date. It is clear that the role of endovascular techniques in the treatment of SFA occlusions is increasing. It remains that, lower risk patients with claudication should be examined to assess the quality of veins suitable for revascularization and bypass should be selected as the first method of choice.

    Heavily calcific lesions, total occlusions, tortuous blood vessels, variable lengths of arteries, various dynamic loads and deformations in the femoropopliteal (FP) arterial segment make stenosis treatments are complicated. The dynamic forces in FP artery including bending, torsion and radial compression may lead to stent fracture (SF) and eventually to in-stent restenosis (ISR). Stent design specifically geometrical configurations are a major factor need to be improved to optimize stent expansion and flexibility both bending and torsion during stent deployment into the diseased FP artery. Previous studies discovered the influence of various stent geometrical designs resulted different structural behaviour. Optimizing stent design can improve stent performances: flexibility and radial strength to prevent SF in FP arterial segment

    Full Text Available Abstract Introduction Popliteal artery aneurysms are the most common peripheral arterial aneurysms, and are frequently bilateral. Acute limb ischemia, rupture and compression phenomena can complicate these aneurysms when the diameter exceeds 2 cm. Case Presentation We report an 82-year-old male patient with two giant femoropopliteal aneurysms, 10.5 and 8.5 cm diameters, managed in our institution. Both aneurysms were resected and a polytetrafluoroethylene (PTFE femoropopliteal interposition graft was placed successfully. Management and literature review are discussed. Conclusion We believe this is the first report in the medical literature of bilateral giant femoropopliteal aneurysms.

    Full Text Available Abstract Despite consensus regarding the interference of cognitive processes on the human balance, the impact that different sensory stimuli have on the stabilometric measures remains unclear. Here, we investigated changes in the postural balance of individuals with Alzheimer's disease (AD and in healthy controls undergoing different proprioceptive and somesthetic pitfalls. We included 17 subjects submitted to eight sensorimotor dynamics with differences in the support bases, contact surfaces, and visual clues. The measurements used to assess participants balance were as follows: position of the body in space, range of instability, area of the support base, and velocity of postural control. From a total of 56 cross-sectional analyses, 21.42% pointed out differences between groups. Longitudinal analyses showed that tasks with proprioceptive and somesthetic pitfalls similarly impact imbalance in both groups. The current results suggest that AD subjects and healthy controls had different patterns submitted to balance, but suffered similar interference when undergoing proprioceptive and somesthetic challenges.

    Favorable long-term outcomes of the Zilver PTX drug-eluting stent (DES) in femoropopliteal lesions have been demonstrated. Chronic renal failure (CRF) has been shown to be a risk factor for restenosis and decreased limb salvage. The results of the DES in patients with CRF have not previously been reported. This study compares the results with the DES in patients with CRF and those without CRF. This retrospective analysis from the Zilver PTX Japan Post-Market Surveillance Study included 321 patients with CRF and 584 patients without CRF. Outcomes included freedom from target lesion revascularization (TLR) and patency. Of the patients included in this subgroup analysis, 2-year data were available for 209 patients in the CRF group and 453 patients in the non-CRF group. The two groups were similar in terms of lesion length and the frequency of in-stent restenosis. Critical limb ischemia, severe calcification, and diabetes were more common in patients with CRF, whereas total occlusion was more common in patients without CRF. Freedom from TLR rates were 81.4 versus 84.9% (p = 0.24), and patency rates were 70.7 versus 70.3% (p = 0.95) in patients with and without CRF at 2 years, respectively. This is the first comparative study of the DES in femoropopliteal artery lesions in patients with and without CRF. These results indicate that the DES placed in femoropopliteal artery lesions of CRF patients is safe and effective with similar patency and TLR rates to patients without CRF.

    Rotational atherectomy with the use of the JetStream XC device is indicated for treatment of infrainguinal arterial obstructive disease. The number of blades-up (BU) runs needed for optimal tissue debulking in femoropopliteal in-stent restenosis (ISR) is unknown. In the present series, 6 patients (15 lesions) were treated for femoropopliteal ISR with the JetStream XC device. Minimal luminal diameter or percent stenosis improved significantly from baseline after 2 BU runs, but no further gain was seen between 2 and 4 BU runs (P > .05). However, adjunctive balloon angioplasty reduced percent stenosis significantly following BU runs. In conclusion, the JetStream XC device achieved optimal acute angiographic results in treating femoropopliteal ISR following 2 BU runs and adjunctive balloon angioplasty.

    AIM To evaluate frequency and clinical course of incidental adenocarcinoma in patients with stricturing Crohn's disease (CD). METHODS In this study, consecutive patients, who were operated on for stricturing CD between 1997-2012, were included at an academic tertiary referral center. Demographic data and clinical course were obtained by an institutional database and individual chart review. Besides baseline characteristics, intraoperative findings and CD related history were also recorded. Colorectal cancer was classified and staged according to the Union for International Cancer Control (UICC). RESULTS During the study period 484 patients underwent resections due to stricturing CD. Incidental adenocarcinoma was histologically confirmed in 6 (1.2%) patients (4 males, 2 females). Patients diagnosed with colorectal cancer had a median age of 43 (27-66) years and a median history of CD of 16 (7-36) years. Malignant lesions were found in the rectum (n = 4, 66.7%), descending colon (n = 1, 16.7%) and ileocolon (n = 1, 16.7%). According to the UICC classification two patients were stages as I (33.3%), whereas the other patients were classified as stage IIA (16.7%), stage IIIB (16.7%), stage IIIC (16.7%) and stage IV (16.7%), respectively. After a median follow-up of 2 (0.03-8) years only 1 patient is still alive. CONCLUSION The frequency of incidental colorectal cancer in patients, who undergo surgery for stenotic CD, is low but associated with poor prognosis. However, surgeons need to be aware about the possibility of malignancy in stricturing CD, especially if localized in the rectum. PMID:28210083

    Full Text Available Michael Lichtenberg1, Matthias Käunicke1, Birgit Hailer1,21Cardiovascular Clinic, Vascular Center, Katholisches Klinikum Essen, Germany; 2University of Witten/Herdecke, GermanyAbstract: Acute and subacute ischemia of the legs in acute and subacute femoropopliteal bypass occlusion is a dramatic situation that endangers the survival of the limbs, depending on the severity of the ischemia. Different therapy options like percutaneous mechanical thrombectomy procedures, which include rotational thrombectomy, have become available in recent years, in addition to local lysis and surgical thrombectomy. Surgical thrombectomy using the Fogarty catheter technique, in particular, shows an increased incidence of perioperative complications but only small technical success rates in randomized trials. On the other hand, local lysis is associated with increased costs due to resource-consuming measures, such as intensive monitoring and repeat angiographies, in addition to bleeding complications. In the past, further development of the Straub Rotarex® system as an endovascular therapy option has demonstrated good success leading to amputation-free survival in multiple studies. At the same time, a low rate of complications with use has been documented. Most examinations have been conducted in the thigh. To date, there are little investigational data on its use in acutely and subacutely occluded femoropopliteal bypasses. In this paper, the current study-based significance of the Rotarex system for this indication is analyzed based on the existing literature and the authors' own experiences with 22 patients.Keywords: acute limb ischemia, femoropopliteal bypass, local lysis, rotational thrombectomy

    Full Text Available Background: Cienfuegos has a high prevalence of chronic kidney disease, which is a health problem of great social and economic impact. Objective: to characterize patients with chronic kidney disease receiving hemodialysis. Methods: a cross-sectional study was conducted in 80 patients treated at the Specialized Outpatient Center of Cienfuegos in 2013. General variables such as age, sex, and place of origin were analyzed, in addition to the causes of the disease, length of time on hemodialysis, type of vascular access, and prevalence of hepatitis C. Absolute frequencies, percentages, and rates were calculated. Results: the 45 to 54 age group was the most affected by the condition. Males accounted for 63.7%. Cienfuegos municipality showed the highest prevalence with 27.6 per 100 000 inhabitants. The most common cause of chronic kidney disease was nephroangiosclerosis (33.3%. Seventy three percent of patients started hemodialysis as an emergency therapy. The time on hemodialysis was less than one year and one to two years in more than half of patients. An arteriovenous fistula was used in 81.3% of cases. Hepatitis C showed a high prevalence. Conclusion: renal disease is more common in men of working age in Cienfuegos municipality. The major causes of this disease are associated with hypertension and diabetes mellitus.

    Background Few studies with contradictory results have been published on the safety of pelvic radiation therapy (RT) in patients with inflammatory bowel disease (IBD). Methods From 1989 to 2015, a single center retrospective analysis was performed including all IBD patients who received pelvic external beam radiation therapy (EBRT) or brachytherapy (BT) for a pelvic malignancy. Treatment characteristics, IBD activity and gastrointestinal (GI) toxicity were examined. Results Overall, 28 patients with Crohn’s disease (CD) (n=13) or ulcerative colitis (n=15) were included in the present study. Median follow-up time after irradiation was 5.9 years. Regarding IBD activity, only one and two patients experienced a severe episode within and after 6 months of follow-up, respectively. Grade 3/4 acute GI toxicity occurred in 3 (11%) patients, whereas one (3.6%) patient experienced late grade 3/4 GI toxicity. Only patients with rectal IBD location (P=0.016) or low body mass index (BMI) (P=0.012) experienced more severe IBD activity within or after 6 months following RT, respectively. Conclusions We report an acceptable tolerance of RT in IBD patients with pelvic malignancies. Specifically, a low risk of uncontrolled flare-up was observed. PMID:28280621

    Background: Magnetic resonance (MR)-guided vascular interventions are of increasing interest, and, with the use of contrast-enhanced techniques, intraarterial contrast-enhanced MR angiography (ia-ce-MRA) competes with intraarterial digital subtraction angiography (ia-DSA) for the diagnostic evaluation of the infrainguinal vessel tree. Purpose: To assess the diagnostic value of ia-ce-MRA and high-resolution T1-weighted (hr-T1w) imaging compared to the gold-standard ia-DSA for residual stenosis and local dissections after femoropopliteal recanalization in patients with peripheral arterial occlusive disease (PAOD). Material and Methods: Eight patients with PAOD and short vessel occlusion of their femoropopliteal arteries underwent recanalization and balloon positioning under DSA. Patients were transferred to a short-bore MR scanner. Percutaneous transluminal angioplasty (PTA) was accomplished under MR fluoroscopy. Pre- and postinterventional ia-ce three-dimensional (3D) gradient-echo MRA with gadopentate dimeglumine was performed using the intraarterial introducer sheath. Maximum intensity projections (MIP) and multiplanar reconstructions (MPR) were calculated from the data set. High-resolution T1w images of the angioplasty region before and after dilatation were acquired. Control ia-DSA images were obtained. Results: The postinterventional angioplasty results for stenosis grading were comparable in ia-MRA and ia-DSA. Only two of five local dissections in ia-DSA were visualized with the ia-ce-MRA runs including MIPs and MPRs. To clearly depict dissection, hr-T1w images were needed. Conclusion: Grading of stenotic lesions with ia-ce-MRA after PTA is comparable to ia-DSA. Intraarterial ce-MRA with calculated MIPs and MPRs is only partially sufficient to visualize local dissections after PTA. High-resolution T1w images are required for precise diagnosis of dissections in magnetic resonance tomography

    Background: Magnetic resonance (MR)-guided vascular interventions are of increasing interest, and, with the use of contrast-enhanced techniques, intraarterial contrast-enhanced MR angiography (ia-ce-MRA) competes with intraarterial digital subtraction angiography (ia-DSA) for the diagnostic evaluation of the infrainguinal vessel tree. Purpose: To assess the diagnostic value of ia-ce-MRA and high-resolution T1-weighted (hr-T1w) imaging compared to the gold-standard ia-DSA for residual stenosis and local dissections after femoropopliteal recanalization in patients with peripheral arterial occlusive disease (PAOD). Material and Methods: Eight patients with PAOD and short vessel occlusion of their femoropopliteal arteries underwent recanalization and balloon positioning under DSA. Patients were transferred to a short-bore MR scanner. Percutaneous transluminal angioplasty (PTA) was accomplished under MR fluoroscopy.

    The vascular anastomoses are usually made with sutures. Some mainly experimental studies have been published about a new method of doing the vascular anastomoses with metal clips. We studied the suitability of vascular closure staple (VCS) clip applier system for making the anastomoses in femoropopliteal and femorotibial arterial reconstruction. During an 11-month period, VCS clips were used in 17 out of 27 patients who were operated due to severe claudication or incipient gangrena of the foot. Altogether 26 anastomoses were made with VCS clips using either great saphenous vein or PTFE graft. The making of anastomosis was easy and reliable. No postoperative bleeding was noticed. All anastomoses were patent 4-6 weeks postoperatively studied by palpation and measured by ankle brachial pressure index (mean 0.96). In Duplex Doppler examination all studied patients had well patent anastomoses on an average 11 months after the operation. With VCS clip applier system, it is possible to do anastomoses in arteriosclerotic arteries like in femoropopliteal reconstructions. This method helps making reliable anastomoses more easily.

    Femoropopiteal artery stenting is a common procedure suggested by medical expert especially for patient who is diagnosed with severe stenosis. Many researchers reported that the growth of stenosis is significantly related to the geometry of stent strut configuration. The different shapes of stent geometry are presenting the different flow pattern and re-circulation in stented femoropopliteal artery. The blood flow characteristics near to the stent geometry are predicted for the possibility of thrombosis and atherosclerosis to be formed as well as increase the growth of stenosis. Thus, this study aims to determine the flow characteristic near to stent strut configuration based on different hemodynamic parameters. Three dimensional models of stent and simplified femoropopliteal artery are modelled using computer aided design (CAD) software. Three different models of stent shapes; hexagon, circle and rectangle are simulated using computational fluid dynamic (CFD) method. Then, parametric study is implemented to predict the performance of stent due to hemodynamic differences. The hemodynamic parameters considered are pressure, velocity, low wall shear stress (WSSlow) and wall shear stress (WSS). From the observation, flow re-circulation has been formed for all simulated stent models which the proximal region shown the severe vortices. However, rectangular shape of stent strut (Type P3) shows the lowest WSSlow and the highest WSS between the range of 4 dyne/cm2 and 70 dyne/cm2. Stent Type P3 also shows the best hemodynamic stent performance as compare to others. In conclusion, Type P3 has a favourable result in hemodynamic stent performance that predicted less probability of thrombosis and atherosclerosis to be formed as well as reduces the growth of restenosis.

    Epidemiologic evidence suggests a link between psychosocial risk factors such as marital status and coronary artery disease (CAD). Polygamy (multiple concurrent wives) is a distinct marital status practiced in many countries in Asia and the Middle East, but its association with CAD is not well defined. We conducted a multicenter, observational study of consecutive patients undergoing coronary angiography during the period from April 1, 2013, to March 30, 2014. Of 1,068 enrolled patients, 687 were married men. Polygamy was reported in 32% of married men (1 wife: 68%, 2 wives: 19%, 3 wives: 10%, and 4 wives: 3%). When stratified by number of wives, significant baseline differences were observed in age, type of community (rural versus urban), prior coronary artery bypass grafting (CABG), and household income. After adjusting for baseline differences, there was a significant association between polygamy and CAD (adjusted OR 4.6 [95% CI 2.5, 8.3]), multivessel disease (MVD) (adjusted OR 2.6 [95% CI 1.8, 3.7]), and left main disease (LMD) (adjusted OR 3.5 [95% CI 2.1, 5.9]). Findings were consistent when the number of wives was analyzed as a continuous variable. In conclusion, among married men undergoing coronary angiography for clinical indications, polygamy is associated with the presence of significant CAD, MVD, and LMD. PMID:28250991

    The purpose of this study was to conduct a systematic review of the available evidence on sleep disorders in patients with end stage renal disease (ESRD) undergoing hemodialysis (HD). [Subjects and Methods] Two independent reviewers performed a computer-assisted search of the MEDLINE, SciELO, LILACS, and BIREME Virtual Health Library medical databases from their inception to November 2015. [Results] One thousand one hundred twenty-six articles were found that met the inclusion criteria. Articles were excluded if they were not in English, the patients did not undergo HD, or the studies were not cross-sectional or clinical trials. After reading the full text, a further 300 studies were excluded because they did not use polysomnography. The remaining 18 studies with ESRD patients undergoing HD comprised 8 clinical trials and 10 cross-sectional studies. This systematic review followed the criteria outlined by the PRISMA declaration. [Conclusion] In this systematic review, a high prevalence of sleep disorders was observed in ESRD, including sleep-disordered breathing. This knowledge may enable health professionals to devise new strategies for the diagnosis and treatment of these patients, in order to reduce morbidity and mortality and improve their quality of life.

    To design and validate an instrument to assess the relevance of educational programs for parents of children with congenital heart disease (CHD) undergoing cardiac surgery. In October 2011, an instrument was designed based on Kaufman's model and on the bibliography, and a survey was developed in the form of a checklist with 32 close-ended questions about received education and desired education, categorized into 5 items: educator, time, place, means, and content. The survey was reviewed by 4 academic professionals and 9 experts in the care of children with CHD, and the checklist was extended to include 42 close-ended questions and 5 open questions. The instrument was administered on the day before discharge to the parents of children with CHD undergoing cardiac surgery at the Department of Pediatrics between February and August 2013. The survey was self-administered by the first participants and administered by the investigator among the remaining participants. Fifty-five children met inclusion criteria; a total of 60 parents took part in the study. Agreement was observed between received education and desired education, which was statistically significant only in terms of education provided by a cardiologist (p= 0.000, K= 0.659) and in the hall (p= 0.000, K= 0.655). Statistically significant differences were observed between the 19 self-administered surveys and the 41 surveys administered by the investigator. Among the latter, a greater level of completion was observed for all items. A validated instrument was developed to assess the relevance of educational programs for parents of children with CHD undergoing cardiac surgery. This survey should be administered by a health care provider for a better understanding of information.

    Adults with hemophilia A (HA), hemophilia B (HB), and von Willebrand disease (VWD) frequently require surgery and invasive procedures. However, there is variability in perioperative management guidelines. We describe our periprocedural outcomes in this setting. A retrospective chart review from January 2006 to December 2012 of patients with HA, HB, and VWD undergoing surgery or invasive procedures was conducted. Type of procedures, management including the use of continuous factor infusion, and administration of antifibrinolytics were reviewed. Adverse outcomes were defined as acute bleeding (patients with HA and HB. In all, 24 patients had severe hemophilia and 12 had mild/moderate hemophilia. Twelve patients had inhibitors. There were also 5 female carriers of HA and 6 patients with VWD. There were 34 major surgeries (26 orthopedic, 8 nonorthopedic) and 129 minor surgeries. Continuous infusion was used in 55.9% of major surgeries versus 8.5% of minor surgeries. Antifibrinolytics were administered in 14.7% of major surgeries versus 23.2% of minor surgeries. In all, 4 patients developed acute bleeding and 10 patients developed delayed bleeding. Delayed bleeding occurred in 28.6% of genitourinary procedures and in 16.1% of dental procedures. Five patients acquired an inhibitor and 2 had thrombosis. In conclusion, patients with HA, HB, or VWD had similar rates of adverse outcomes when undergoing minor surgeries or major surgeries. This finding underscores the importance of an interdisciplinary management and procedure-specific guidelines for patients with hemophilia and VWD prior to even minor invasive procedures.

    Whole-body gamma camera counting is an alternative to faecal {sup 111}In collection for quantifying disease activity in inflammatory bowel disease (IBD) but requires administration of imaging activities of {sup 111}In. The aim of this study was to explore a dedicated whole-body counter which requires 20-fold less activity than gamma camera counting. Thirty patients with known or suspected IBD received {sup 99m}Tc-granulocytes ({proportional_to}200 MBq) and {sup 111}In-granulocytes ({proportional_to}0.5 MBq). The {sup 99m}Tc-cells were injected 45 min after the {sup 111}In-cells and immediately after a baseline {sup 111}In whole-body count. The decay-corrected count at 120 h was expressed as a fraction of baseline to give whole-body {sup 111}In retention (WBR). One patient was excluded as the injected cells were non-viable. Median 45-min intravascular {sup 111}In recovery was 35% in patients compared with 43% in six normal volunteers (p<0.05). WBR in normals ranged from 91% to 93% and in 11 patients with negative {sup 99m}Tc imaging from 87% to 96%. Only one of 11 patients with negative imaging had WBR <90% while 11/12 patients with WBR <90% had abnormal imaging. Ten of 13 patients with Crohn's disease (CD) had abnormal imaging. The lowest WBR in these ten was 77% and six had values of >90%. There was a significant association between WBR and {sup 99m}Tc image grade (R{sub s}=0.73, p<0.002) in 16 patients without CD, but not in 13 patients with CD (R{sub s}=0.54, p>0.05). Dedicated whole-body counting is able to quantify disease activity in IBD but may give normal values in active CD. (orig.)

    In the present study, a comparative evaluation of the effects of calcium acetate, calcium carbonate, sevelamer hydrochloride and lanthanum carbonate was carried out in 120 patients with end stage kidney disease (ESKD) undergoing hemodialysis. Biochemical parameters, like serum phosphorous, serum calcium and serum alkaline phosphatase level and intact parathyroid hormone level, were measured. A statistically significant reduction in serum phosphorous, serum calcium, calcium × phosphorous and serum alkaline phosphatase level were observed with all phosphate binders during 3 months of treatment. Reduction in serum phosphorous were observed with calcium acetate (1.5 mg/dL), calcium carbonate (1.3 mg/dL), sevelamer hydrochloride (2.1 mg/dL) and lanthanum carbonate (1.79 mg/dL). The reduction of serum alkaline phosphatase was observed more commonly with sevelamer (107.37 IU/L) and lanthanum (104.33 IU/L) treatments than with calcium acetate (93.9 IU/L) and calcium carbonate (86.57 IU/L). There was no statistically significant change in serum calcium observed with sevelamer and lanthanum treatments, while calcium-based phosphate binders caused a significant rise in the serum calcium level. Serum intact parathyroid hormone level was significantly reduced with all phosphate binder treatments. This decline was highest with sevelamer and lowest with calcium carbonate. All treatments were well tolerated and safety profiles were consistent with previous reports in hemodialysis patients. It is concluded that all phosphate binders are safe and effective for the treatment of hyperphosphatemia in patients with ESKD undergoing hemodialysis. However, sevelamer hydrochloride seems to be superior among all with lowering incidence of hypercalcemia.

    Purpose: To evaluate early patency rate of the heparin-bonded stent grafts in atherosclerotic long femoropopliteal occlusive disease, and to identify factors that affect outcome. Methods: Heparin-bonded Viabahn stent grafts were placed in 33 limbs in 33 patients during 2009-2010. The stents were deployed to rescue failed conventional balloon angioplasty. Mean age was 69 (range 44-88) years, and 67 % (22 of 33) were men. Most procedures (21 of 33, 64 %) were performed for critical limb ischemia (33 % for rest pain, 30 % tissue loss). Kaplan-Meier plots and Cox regression analysis were used to identify significant risk factors. Results: The average length of lesions treated was 25 {+-} 10 cm, and they were predominantly TASC (Transatlantic Intersociety Consensus) D (n = 13) and C (n = 17) lesions. The median primary patency was 5.0 months (95 % confidence interval 1.22-8.77). The mean secondary patency was 8.6 months (95 % confidence interval 6.82-10.42). Subsequently, 4 patients underwent bypass surgery and 5 patients underwent major amputation. One patient died. There were 5 in-stent or edge-stent stenoses. Cox multivariate regression analysis identified TASC D lesions to be a significant risk factor for early occlusion (p = 0.035). Conclusion: TASC D lesions of femoropopliteal occlusions have poor patency rates with the use of heparin-bonded stent grafts after failed conventional angioplasty. Alternative options should be considered for these patients.

    Surgical therapy has been proven to be the mainstay of treatment for hepatic metastases from colorectal cancer (CRM) in the appropriate patient. Previous contraindications were patients with extrahepatic disease (EHD) do not benefit from liver resection or ablation. We hypothesized that the survival of patients with EHD who receive aggressive multimodality care would be the same as those without EHD. A review of our 1305 patient prospective hepato-pancreatico-biliary database from August 1995 to April 2008 identified 383 patients with surgical management of metastatic CRM to the liver. A total of 39 patients with limited EHD underwent liver resection/ablation vs 344 patients without EHD. There were no significant differences in hepatic disease burden (mean clinical risk score of 2.3 and 2.1 in patients with and without EHD, P=.19, and median number of hepatic metastases of 2 in each group, P=.88) or size of the largest lesion (mean 4.6 vs 4.5 cm with and without EHD, P=.84). EHD consisted of lung metastases in 33%, nodal metastases in 21%, peritoneal in 15%, unknown in 15%, and other in 15%. There was no difference in patients with and without EHD undergoing surgical with resection only in 41% vs 48%, ablation only in 31% vs 30%, and combined resection and ablation in 28% vs 22% (P=.61). Overall survival in patients with EHD was not significantly different (median survival 24 vs 33 months, P=.06). A thorough understanding of the biology of disease and appropriate multimodality care can lead to improved survival in patients with EHD, when compared with chemotherapy alone.

    Since the surgery for congenital heart disease (CHD) is considered highly risky, appropriate postoperative care is crucial. After the surgery, children are often discharged with unhealed wounds, incomplete recovery, and continuing pain. Health education programs based on empowerment education model can assist clients to develop skills in self-management. This study aimed to evaluate the effectiveness of an empowerment health education program for improving caregiving knowledge, caring behaviors, and self-efficacy of parents caring for children after corrective surgery for CHD. This prospective clinical trial enrolled pediatric patients undergoing surgical correction for CHD. Patients were divided into two groups: the control group (n = 42), which received the standard education program, and the intervention group (n = 44), which participated in the empowerment theory-based education program. We collected data on left ventricular ejection fraction (LVEF); peripheral oxygen saturation (SpO2); New York Heart Association classification of the patients; and the parents' caregiving knowledge, caring behaviors, and self-efficacy before surgery and one month and three months after surgery. At one month and three months after surgery, the intervention group scored higher than the control group in caregiving knowledge, caring behavior, and self-efficacy. By the third month after surgery, the intervention group had significantly higher values of LVEF and SpO2 than the control group. © The Author(s) 2015.

    Purpose: This study investigates the features of neutropenic enterocolitis (NE) in adults. Materials and Methods: Chart and radiology report reviews were used to identify neutropenic patients with hematological diseases undergoing chemotherapy, who had CT scans for the clarification of abdominal symptoms between October 2003 and October 2009. Patients with any cause for enteritis other than NE were excluded. The scans were analyzed with respect to imaging features and location. Morphological findings were correlated with clinical data. Results: Thirty-one patients with NE (median age 46 years; range 20 - 75) could be identified. Wall thickening and hyperemia could be found in all bowel segments from jejunum to rectum. The right hemicolon was the most frequent location in 19 patients (61 %). Involvement was generalized in 6 patients (19 %) and segmental in 25 cases (81 %). The longer the duration of neutropenia, the more likely generalized involvement of the bowel was. In 8 patients who underwent CT follow-up, the appearance of bowel segments had completely (n = 5) or partially (n = 3) returned to normal at the latest 14 days after the initial diagnosis. Eight patients (26 %) died 1 - 78 days after NE, 7 of who had previously recovered from NE. Conclusion: CT findings are useful for the diagnosis of NE and should be considered even in the presence of isolated small bowel involvement. The terms NE and typhlitis should thus no longer be used synonymously. (orig.)

    Children with sickle cell disease (SCD) often undergo MRI studies to assess brain injury or to quantify hepatic iron. MRI requires the child to lie motionless for 30-60 min, thus sedation/anesthesia might be used to facilitate successful completion of exams, but this poses additional risks for SCD patients. To improve children's ability to cope with MRI examinations and avoid sedation, our institution established preparation and support procedures (PSP). To investigate the impact of PSP in reducing the need for sedation during MRI exams among children with SCD. Data on successful completion of MRI testing were compared among 5- to 12-year-olds who underwent brain MRI or liver R2*MRI with or without receiving PSP. Seventy-one children with SCD (median age 9.85 years, range 5.57-12.99 years) underwent a brain MRI (n = 60) or liver R2*MRI (n = 11). Children who received PSP were more likely to complete an interpretable MRI exam than those who did not 30 of 33; 91% vs. 27 of 38; 71%, unadjusted OR = 4.1 (P = 0.04) and OR = 8.5 (P < 0.01) when adjusting for age. PSP can help young children with SCD complete clinically interpretable, nonsedated MRI exams, avoiding the risks of sedation/anesthesia. (orig.)

    Full Text Available The study was carried out to evaluate the effect of prophylactic single-dose intravenous amiodarone in patients undergoing valve replacement surgery. Maintenance of sinus rhythm is better than maintenance of fixed ventricular rate in atrial fibrillation (AF especially in the presence of irritable left or right atrium because of enlargement. Fifty-six patients with valvular heart disease with or without AF were randomly divided into two groups. Group I or the amiodarone group (n=28 received amiodarone (3 mg/kg in 100 ml normal saline and group II or the control group received same volume of normal saline. The standardized protocol for cardiopulmonary bypass was maintained for all the patients. AF occurred in 7.14% patients in group I, and in group II, 28.57% (P=0.035; ventricular tachycardia/fibrillation was observed in 21.43% patients in group I and 46.43% patients in group II (P=0.089 after release of aortic clamp. Most of the patients in group I (92.86% maintained sinus rhythm without cardioversion or defibrillation after release of aortic cross clamp (P=0.002. Defibrillation or cardio version was needed in 7.14% patients in group I and 28.57% patients in group II (P=0.078. A single prophylactic intraoperative dose of intravenous amiodarone decreased post bypass arrhythmia in this study in comparison to the control group. Single dose of intraoperative amiodarone may be used to decrease postoperative arrhythmia in open heart surgery.

    Prostaglandin E2 (PGE2) is an anti-inflammatory compound that inhibits 5-lipoxygenase activity. Diminished PGE2 regulation in aspirin-exacerbated respiratory disease (AERD) leads to respiratory reactions on cyclooxygenase 1 inhibition. In vitro studies have found that exogenous PGE2 stabilizes inflammatory mediator release. To examine whether misoprostol (oral prostaglandin E1 analogue) use during aspirin challenge and desensitization might decrease the severity of aspirin-induced symptoms and make desensitization safer for patients with AERD. Forty-five patients undergoing aspirin challenge and/or desensitization were randomized to misoprostol (n = 30) or placebo (n = 15) and compared with a group of historical controls (n = 31). Misoprostol (200 μg) was administered at 30 minutes, 90 minutes, and 4 hours after the first dose of nasal ketorolac. Measured end points included change in forced expiratory volume in 1 second (FEV1), peak nasal inspiratory flow rate (PNIF), number of treatments received for induced reactions, and adverse gastrointestinal effects. A difference in FEV1 and PNIF reduction was detected between misoprostol and placebo (P = .03) and misoprostol and historical controls (P = .01), respectively, during nasal ketorolac challenge. No difference was detected among aspirin reactors. Among all reactors, no difference in magnitude was found for FEV1 (P = .13) or PNIF (P = .07) reduction across all 3 groups. Total treatment requirement was similar (P = .14). Patients receiving misoprostol were more likely to report adverse gastrointestinal effects (P = .02). The addition of misoprostol to current aspirin challenge and/or desensitization protocols reveals no protective effect in reducing the intensity of nonsteroidal anti-inflammatory drug-induced symptoms and is not recommended based on the findings in this study.

    Full Text Available Background: Moyamoya disease (MMD is a chronic cerebrovascular disorder, defined as the progressive stenosis or occlusion of the intracranial vessels. Because of the insecure cerebral circulation, these patients represent an anaesthetic challenge. Literature is scarce on the anaesthetic management of MMD, especially from the Indian subcontinent. The main objective of our study was to evaluate the peri-operative course and outcome of patients undergoing surgery for MMD. Materials and Methods: We analysed available medical records of all patients who underwent revascularisation surgeries for MMD over a period of 10 years (January 2002 to June 2012. Various intra- and post-operative data related to anaesthesia were recorded. The patients for the analysis were divided into two groups: Group 1, paediatrics (<18 years and group 2, adults (≥18 years. Data are presented as number (% or mean ± SD or median (range. Results: There were 36 patients (12 adults and 24 children. Normotension, normovolaemia, normo- or mild-hypercapnia and normothermia were maintained in all patients. No patient developed complications or new neurological deficit in the post-operative period. All patients were discharged with a full Glasgow coma scale (GCS and no new neurologic deficit. Conclusion: Although the incidence of MMD is not high in India, it is an important cause of cerebral stroke in children and adults. Proper pre-operative evaluation is the most effective method to achieve good results. Anaesthetic management of MMD should focus on the maintenance of adequate cerebral blood flow and cerebral perfusion pressure ensuring adequate cerebral oxygenation to avoid ischaemic complications.

    Patients who have had multiple previous attempts at limb salvaging surgery frequently go on to have an amputation. This, however, results both in psychological perturbation for the patient and high rehabilitation costs for the community. Successful limb salvage surgery therefore has an important role in vascular surgery. We describe the management of a patient with critical limb ischemia that had previously undergone multiple limb salvage procedures and whose limb was saved by the use of a continuous femoropopliteal crossover bypass graft. The patient, who may have been deemed by some as a candidate for amputation, has full use of his limb 6 months after surgery with ankle brachial pressure index readings of 0.6. Continuous femoropopliteal crossover bypass grafting is a poorly described surgical technique that may be appropriate in a subgroup of patients and may allow salvage of a limb that otherwise may have been deemed fit for amputation.

    High failure rates of femoropopliteal artery reconstruction are commonly attributed to complex 3D arterial deformations that occur with limb movement. The purpose of this study was to develop a method for accurate assessment of these deformations. Custom-made stainless-steel markers were deployed into 5 in situ cadaveric femoropopliteal arteries using fluoroscopy. Thin-section CT images were acquired with each limb in the straight and acutely bent states. Image segmentation and 3D reconstruction allowed comparison of the relative locations of each intra-arterial marker position for determination of the artery's bending, torsion and axial compression. After imaging, each artery was excised for histological analysis using Verhoeff-Van Gieson staining. Femoropopliteal arteries deformed non-uniformly with highly localized deformations in the proximal superficial femoral artery, and between the adductor hiatus and distal popliteal artery. The largest bending (11±3-6±1 mm radius of curvature), twisting (28±9-77±27°/cm) and axial compression (19±10-30±8%) were registered at the adductor hiatus and the below knee popliteal artery. These deformations were 3.7, 19 and 2.5 fold more severe than values currently reported in the literature. Histology demonstrated a distinct sub-adventitial layer of longitudinally oriented elastin fibers with intimal thickening in the segments with the largest deformations. This endovascular intra-arterial marker technique can quantify the non-uniform 3D deformations of the femoropopliteal artery during knee flexion without disturbing surrounding structures. We demonstrate that 3D arterial bending, torsion and compression in the flexed lower limb are highly localized and are substantially more severe than previously reported.

    Full Text Available Objectives: The present study was conducted to evaluate the cardioprotective effect of sevoflurane compared with propofol in patients with coronary artery disease (CAD undergoing peripheral vascular surgery; and to address the question whether a volatile anesthetic might improve cardiac outcome in these patients. Methods: One hundred twenty-six patients scheduled for elective peripheral vascular surgery were prospectively randomized to receive either sevoflurane inhalation anesthesia or total intravenous anesthesia. ST-segment monitoring was performed continuously during intra- and post-operative 48 h periods. The number of ischemic events and the cumulative duration of ischemia in each patient were recorded. Blood was sampled in all patients for the determination of cTnI. Samples were obtained before the induction of anesthesia, on admission to the ICU, and at 6, 12, 24, and 48 h after admission to the intensive care unit (ICU. Patients were followed-up during their hospital stay for any adverse cardiac events. Results: The incidence of ischemia were comparable among the groups [16 (25% patients in sevoflurane group vs 24 (39% patients in propofol group; P=0.126]. Duration, cumulative duration, and magnitude of ST-segment depression of ischemic events in each patient were significantly less in sevoflurane group (P=0.008, 0.048, 0.038, respectively. cTnI levels of the overall population were significantly less in sevoflurane group vs propofol group (P values <0.0001 from 6 h postoperative and onward. Meanwhile, cTnI levels at 6, 12, 24, and 48 h after admission to the ICU in patients who presented with ischemic electrocardiographic (ECG changes were significantly lower in sevoflurane group than in the propofol group (P<0.0001, <0.0001, <0.0001, 0.0003. None of the patients presented with unstable angina, myocardial infarction, congestive heart failure, or serious arrhythmia either during ICU or hospital stay. Conclusion: Patients with CAD

    Background Local recurrence remains a serious problem among patients undergoing breast conservative surgery. This study aimed at identifying risk factors for residual disease after breast conservative surgery.Methods This retrospective study was based on patients with invasive breast cancer who have received breast conservative surgery and subsequent completion mastectomy. All patients had a clear resection margin in the initial operation. We analyzed the association between the presence of residual disease during completion mastectomy and the following risk factors: T staging, young age, and presence of extensive intraductal component (EIC), a close margin, lymphovascular permeation (LVP), positivity of estrogen receptor, progesterone receptor, and c-erbB-2.Results Residual disease was encountered in 21 (45.7%) of 46 patients; EIC was present in 28 patients (60.9%), of whom 17 had residual disease. Presence of EIC during breast conservation surgery was associated with a higher risk of residual disease during completion mastectomy (P=0.011). Other variables were not statistically significant risk factors for presence of residual disease. No local recurrence was recorded in our cohort, and the disease-free survival and overall survival after completion mastectomy were similar for patients who had residual disease and those who had not.Conclusions The presence of EIC is a significant risk factor for residual disease in patients after breast conservative surgery. Our findings may suggest the indicated value of completion mastectomy in patients with EIC during initial breast conservative surgery to decrease the risk of subsequent local failure.

    The management and impact of concomitant coronary artery disease in patients referred for TAVI remains contentious. We describe the prevalence, clinical impact and management of coronary artery disease (CAD) in patients in the United Kingdom TAVI Registry. All-inclusive study of patients undergoing TAVI in the United Kingdom (excluding Northern Ireland) from January 2007 to December 2011. Coronary artery disease at the time of TAVI was demonstrated on invasive angiography. 2588 consecutive patients were entered in the U.K. TAVI Registry. CAD was reported in 1171 pts with left main stem involvement in 12.4% of this cohort (n=145). Most patients were free of chest pain, but limited by dyspnoea (NYHA Class III & IV 81.9%). Angina was however more prevalent in those patients with CAD (pdisease management in an "all-comers" patient population undergoing TAVI demonstrates that whilst often an indicator of significant underlying comorbidity coronary artery disease is not associated with decreased short or long-term survival. The majority of patients with aortic stenosis and concomitant CAD can be managed effectively by TAVI alone. However, the importance of the Heart Team in making decisions on individual patients must not be underestimated. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Full Text Available Abstract Background Endovascular treatment options for the superficial femoral artery are evolving rapidly. For long lesions, the venous femoropopliteal bypass considered to be superior above the prosthetic bypass. An endoluminal bypass, however, may provide equal patency rates compared to the prosthetic above knee bypass. The introduction of heparin-bonded endografts may further improve patency rates. The SUrgical versus PERcutaneous Bypass (SuperB study is designed to assess whether a heparin-bonded endoluminal bypass provides equal patency rates compared to the venous bypass and to prove that it is associated with improved quality of life, related to a decreased complication rate, or not. Methods/design Two-hundred-twenty-two patients with peripheral arterial occlusive disease, category 3-6 according to Rutherford, will be randomized in two treatment arms; 1. the surgical femoro-popliteal bypass, venous whenever possible, and 2. the heparin-bonded endoluminal bypass. The power analysis was based on a non-inferiority principle, with an effect size of 90% and 10% margins (alpha 5%, power 80%. Patients will be recruited from 5 teaching hospitals in the Netherlands during a 2-year period. The primary endpoint is primary patency and quality of life evaluated by the RAND-36 questionnaire and the Walking Impairment Questionnaire. Secondary endpoints include secondary patency, freedom-from-TLR and complications. Discussion The SuperB trial is a multicentre randomized controlled trial designed to show non-inferiority in patency rates of the heparin-bonded endograft compared to the surgical bypass for treatment of long SFA lesions, and to prove a better quality of life using the heparin bonded-endograft compared to surgically treatment, related to a reduction in complications.

    Kidney disease and cardiovascular disease seem to be lethally synergistic and both are approaching the epidemic level. A reduced glomerular filtration rate is associated with increased mortality risk in patients with heart failure. Many patients with congestive heart failure are anemic. Anemia is very often associated with chronic kidney disease. To assess--in relation to New York Heart Association class--the prevalence of anemia and chronic kidney disease in patients with normal serum creatinine in a cohort of 526 consecutive patients with coronary artery disease undergoing percutaneous coronary interventions. GFR was estimated using the simplified MDRD formula, the Cockcroft-Gault formula, the Jeliffe and the novel CKD-EPI formula. According to the WHO definition the prevalence of anemia in our study was 21%. We observed a progressive decline in GFR and hemoglobin concentration together with a rise in NYHA class. Significant correlations were observed between eGFR and systolic blood pressure, diastolic blood pressure, age, NYHA class, complications of PCI, including bleeding, and major adverse cardiac events. The prevalence of anemia and chronic kidney disease is high in patients undergoing PCI despite normal serum creatinine, particularly in higher NYHA class. Lower eGFR and hemoglobin are associated with more complications, including bleeding after PCI and higher prevalence of major adverse cardiac events. In patients with risk factors for cardiovascular disease, GFR should be estimated since renal dysfunction and subsequent anemia are important risk factors for cardiovascular morbidity and mortality.

    Full Text Available Background: This study reported the incidence and prognostic outcome of chronic obstructive lung disease (COPD patients with acute ST-segment elevation myocardial infarction (STEMI undergoing primary percutaneous coronary intervention (PCI. Methods: Between January 2002 and May 2011, totally 1554 consecutive patients who experienced STEMI undergoing primary PCI were enrolled into the study. Results: Of the 1554 patients, 124 (9.7% with diagnosis of COPD and 1430 (90.3% without COPD were categorized into group 1 and group 2. Although no difference in in-hospital mortality was noted between the two groups (p = 0.726. However, the hospitalization duration was notably longer (p = 0.003, the incidences of recurrent MI and re-hospitalization for congestive heart failure were significantly higher in group 1 than in group 2 (all p < 0.02. Although Kaplan-Meier analysis demonstrated that the incidence of freedom from one-year major adverse clinical outcome (MACO (defined as recurrent MI, re-admission for congestive heart failure was significantly lower in group 1 than group 2 (p = 0.012, multivariate Cox regression analysis showed COPD was not an independent predictor of MACO-free time after adjusting traditional risk factors. Conclusion: COPD was not an independent predictor of short-term and medium-term MACO in patients with STEMI undergoing primary PCI.

    Adults with congenital heart disease (ACHD) undergoing systemic atrioventricular valve (SAVV) surgery are a complex, understudied population. We assessed midterm outcomes and prognostic factors in ACHD undergoing SAVV surgery. We performed retrospective evaluation of ACHD undergoing SAVV surgery from January 2005 to February 2016: 14 (33%) patients with congenital mitral valve stenosis/regurgitation, 15 (35%) with atrioventricular septal defect (AVSD), and 14 (33%) with congenitally corrected transposition of the great arteries (ccTGA) with systemic tricuspid valve regurgitation. Adverse events were defined as mortality, reoperation on SAVV, and late more-than-moderate (> moderate) SAVV regurgitation. Statistical analysis was performed using Fisher's exact test and one-way analysis of variance as well as univariate and multivariate risk factor analysis. Fifteen (35%) patients had preoperative systemic ventricular dysfunction, including 13 patients with ccTGA (93%, P moderate SAVV regurgitation, and SAVV reoperation rates were 5% (n = 2), 2% (n = 1), 9% (n = 3), and 7% (n = 3), respectively. On multivariate analysis, predischarge SAVV regurgitation grade was the only significant predictor of adverse events (odds ratio = 8.2, 95% confidence interval: 1.1-63.8, P = .045). Overall outcomes in this challenging population are good. The single factor associated with adverse events was predischarge SAVV regurgitation grade.

    Previous reports describing the prevalence of ear diseases in dogs have primarily been based on dogs presenting with clinical signs of disease. The prevalence of subclinical ear disease remains unknown. The purpose of this cross-sectional retrospective study was to describe the prevalence of lesions consistent with middle and external ear disease in dogs presented for multidetector computed tomography (CT) of the head and/or cranial cervical spine at our hospital during the period of July 2011 and August 2013. For each included dog, data recorded were signalment, CT findings, diagnosis, and treatment. A total of 199 dogs met inclusion criteria. Nineteen dogs (9.5%) were referred for evaluation of suspected ear disease and 27 dogs (13.5%) had histories or physical examination findings consistent with otitis externa. A total of 163 dogs (81.9%) had CT lesions consistent with external ear disease (i.e. ear canal mineralization, external canal thickening, and/or narrowing of the external canal). Thirty-nine dogs (19.5%) had CT lesions consistent with middle ear disease (i.e. soft tissue attenuating/fluid material in the tympanic bullae, bulla wall thickening or lysis, and/or periosteal proliferation of the temporal bone). Findings from this study indicated that the prevalence of external and middle ear disease in dogs could be higher than that previously reported.

    Cytomegalovirus infection and disease is associated with poor prognosis and steroid refractoriness in inflammatory bowel disease patients. The unfavourable effect of steroids and immunosuppressive therapy on CMV infection is well known but few data are available concerning anti-TNFalpha therapy (Infliximab). Aim of the study was to evaluate the presence and severity of CMV infection and disease in Infliximab-treated IBD patients. The severity of active CMV infection and disease was assessed in 11 consecutive patients with ileocolonic/colonic disease and 4 patients with ulcerative colitis before and after a standard 3-infusion course of Infliximab. Active CMV infection was evaluated by serology and diagnosed by means of pp65-antigenemia (pp65 AG), and quantification of CMV DNA isolated from biopsy specimens of colonic tissue. CMV disease was assessed on haematoxylin/eosin-stained colonic biopsies and immunohistochemical stains. Of the 11 patients, nine were CMV seropositive. As far as concerns CMV infection, only one patient had positive pp65 AG, before and after Infliximab. CMV DNA was detected in the colonic biopsies of three patients. In 2, CMV DNA persisted also after therapy with 410 and 1300 copies/microg of DNA, respectively, albeit with no evidence of worsening of the colonic disease. In the remaining patient, CMV DNA load became undetectable. Conventional histology and immunohistochemical stains were negative for CMV in all the patients, without evidence of CMV disease. Active CMV infection did not progress to disease following Infliximab therapy. Although these preliminary observations require confirmation, the response to Infliximab therapy does not appear to be influenced by, or influence the course of, CMV infection/disease.

    Full Text Available Background: thyroid disease is one of the most prevalent medical conditions and thyroid cancer is the most common endocrine neoplasm. Thyroid reoperations are more common than it might seem.Objective: to establish the clinical and epidemiological characteristics of patients operated on for colloid goiter undergoing reoperation for recurrent thyroid disease.Methods: a case-series study was conducted at the León Cuervo Rubio Clinical-Surgical Hospital in Pinar del Rio. The sample included all patients (n = 29 who underwent thyroid operation and were reoperated on for recurrent thyroid disease in 2010, 2011 and 2012. The information was obtained from medical records and the register of histopathological diagnoses.Results: most patients (27.6% were in the 40-49 age group and females (79.3% were most affected. Recurrence was observed 5 to 9 years after surgery. Mixed nodules (55.2% followed by cysts (17.2% were the most frequent ultrasound diagnoses. Recurrent thyroid disease was malignant in 9% of patients.Conclusions: patients reoperated on for thyroid disease were mostly females in the fourth and fifth decade of life. The disease recurred in a period of 10 years after the first surgery in a greater number of cases. Follicular-patterned lesions, colloid goiter and cancer were the most common histologic diagnosis.

    We report on two additional cases of metformin-associated encephalopathy in patients with end-stage renal disease (ESRD) undergoing hemodialysis. Two patients were seen at our hospital with abnormal neurological signs and symptoms. Magnetic resonance imaging (MRI) revealed the same pattern of high signal intensity in both basal ganglia in T2-weighted images in the two patients. The two patients had started taking metformin 5 and 6 weeks earlier at the same dose of 1000 mg per day. Metformin was immediately stopped, and regular hemodialysis was conducted. Their signs and symptoms resolved completely after these measures. The high signal intensity in both ganglia in T2-weighted MRI also disappeared. We should suspect metformin-induced encephalopathy and withdraw the drug when presented with diabetic patients with chronic kidney disease and neurological signs and symptoms of unknown cause.

    Full Text Available End stage liver disease is often associated with growth retardation in children with congenital and hereditary diseases of hepatobiliary system. The aim was to investigate the serum growth hormone level before and after liver transplantation in 52 children with congenital and hereditary diseases of hepatobiliary system. Data of our research work revealed increased serum level of growth hormone in children with liver cirrhosis (3,32 ± 7,7 ng/ml vs. 1,16 ± 1,46 ng/ml in healthy children, p = 0,01, which correlates with PELD score (r = 0,62, p < 0,001. In a month after liver transplantation growth hormone concentration decreases (p < 0,001 and in a year after transplantation it doesn’t differ from healthy children. There wasn’t revealed any interaction between serum growth hormone level and anthropometric parameters before liver transplantation, but in a year after there was significant correlation between growth hormone concentration and height (r = 0,79, p = 0,01. Investigation of growth hormone level in children with liver cirrhosis and its evolution after liver transplantation is of interest as objective criterion of recovery of physical development regulation and as an additional parameter, which cor- relates with severity of end-stage liver disease

    Full Text Available Familial hypercholesterolemia is characterized by high serum levels of total cholesterol and LDL-cholesterol. It may be homozygous or heterozygous. In homozygous patients, LDL-cholesterol levels range from 500 to 1000mg/dL and coronary artery disease is precocious, usually manifesting itself between the 2nd and 3rd decades of life. The diagnosis is often made by the presence of xanthoma tuberosum and tendinous xanthomas that appear between the 1st and 2nd decades of life. The use of high doses of statins or even unusual procedures (apheresis, partial ileal bypass surgery, liver transplantation, gene therapy, or both, is necessary for increasing survival and improving quality of life, because a reduction in cholesterol levels is essential for stabilizing the coronary artery disease and reducing xanthomas. We report our experience with 3 patients with xanthomatous familial hypercholesterolemia and coronary artery disease, who underwent partial ileal bypass surgery. Their follow-up over the years (approximately 8 years showed a mean 30% reduction in total cholesterol, with a significant reduction in the xanthomas and stabilization of the coronary artery disease.

    The aim of this study was to review the various anesthetic options which can be considered for laparoscopic surgeries in the patients with the chronic obstructive pulmonary disease. The literature search was performed in the Google, PubMed, and Medscape using key words “analgesia, anesthesia, general, laparoscopy, lung diseases, obstructive.” More than thirty-five free full articles and books published from the year 1994 to 2014 were retrieved and studied. Retrospective data observed from various studies and case reports showed regional anesthesia (RA) to be valid and safer option in the patients who are not good candidates of general anesthesia like patients having obstructive pulmonary diseases. It showed better postoperative patient outcome with respect to safety, efficacy, postoperative pulmonary complications, and analgesia. So depending upon disease severity RA in various forms such as spinal anesthesia, paravertebral block, continuous epidural anesthesia, combined spinal epidural anesthesia (CSEA), and CSEA with bi-level positive airway pressure should be considered.

    Prolonged exposure of humans and animals to increased pressure as in a disabled submarine (DISSUB) can saturate the body's tissues with dissolved N2 as compressed air is breathed. Decompression-induced bubble formation in the long bone marrow cavity may lead to a bone compartment syndrome resulting in bone ischemia and necrosis. We tested oxygen pre-breathing prior to decompression in sheep to assess the effect upon dysbaric osteonecrosis (DON) induction in a DISSUB simulation experiment. A total of sixteen adult female sheep were used throughout the experiment. Four sheep were used as controls without oxygen pre-breathing. All sheep (99 +/- 14 kg SD) underwent dry chamber air exposure at 60 fsw (2.79 atm abs) (.2827 MPa) for 24 h followed by oxygen (88-92%) pre-breathing (15-min, 1-h, and 2-h and air for control) before "dropout" decompression at 30 fsw/min (0.91 atm/min). 99mTc-methylene diphosphonate (MDP) bone scans of the distal (radii and tibiae) long bones were used to detect "hot spots" of remodeling suggestive of DON lesions. Alizarin complexone fluorochrome was injected to visualize sites of metabolic activity indicating DON repair of both the proximal and distal long bones (radii, tibiae, femora, and humeri). Our findings showed that the amount of alizarin complexone deposition and bone scan uptake was greater in sheep with shorter oxygen pre-breathing times than those undergoing longer pre-breathing dives (p = 0.0056 and p = 0.001, for one and two hour pre-breathes respectively). Proximal limb bones (femur, humerus) displayed less alizarin complexone deposition than the distal radius and tibia (p < 0.0001).

    Background The hybrid procedure for coronary heart disease combines minimally invasive coronary artery bypass grafting (CABG) and percutaneous coronary intervention (PCI) and is an alternative to revascularization treatment.We sought to assess the predictive value of four risk-stratification models for risk assessment of major adverse cardiac and cerebrovascular events (MACCE) in patients with multivessel disease undergoing hybrid coronary revascularization.Methods The data of 120 patients were retrospectively collected and the SYNTAX score,EuroSCORE,SinoSCORE and the Global Risk Classification (GRC) calculated for each patient.The outcomes of interest were 2.7-year incidences of MACCE,including death,myocardial infarction,stroke,and any-vessel revascularization.Results During a mean of 2.7-year follow-up,actuarial survival was 99.17%,and no myocardial infarctions occurred.The discriminatory power (area under curve (AUC)) of the SYNTAX score,EuroSCORE,SinoSCORE and GRC for 2.7-year MACCE was 0.60 (95% confidence interval 0.42-0.77),0.65 (0.47-0.82),0.57 (0.39-0.75) and 0.65 (0.46-0.83),respectively.The calibration characteristics of the SYNTAX score,EuroSCORE,SinoSCORE and GRC were 3.92 (P=0.86),5.39 (P=0.37),13.81 (P=0.32) and 0.02 (P=0.89),respectively.Conclusions In patients with multivessel disease undergoing a hybrid procedure,the SYNTAX score,EuroSCORE,SinoSCORE and GRC were inaccurate in predicting MACCE.Modifying risk-stratification models to improve the predictive value for a hybrid procedure is needed.

    The objective of this study was to identify risk factors for suboptimal medical therapy (defined as reported antiplatelet and statin use) among patients undergoing lower extremity bypass (LEB) and peripheral vascular interventions (PVIs) for symptomatic peripheral arterial disease (PAD). The Vascular Study Group of Greater New York (VSGGNY) database was used to identify all patients undergoing PVI or LEB for PAD (2011-2013). Bivariate analyses were performed to identify characteristics of patients who were not prescribed statins and/or antiplatelet agents before revascularization. Multivariate relative risk regression models were developed to identify patients at risk for suboptimal therapy, with regards to antiplatelet and statin therapy. About 1,030 patients underwent endovascular therapy (n = 822; 80%) or surgical bypass (n = 208; 20%) for symptomatic PAD (57.2% claudication; 15% rest pain and 27.8% tissue loss). Overall, preoperative statin use was observed in 59%. Preoperative antiplatelet therapy was observed in 79% of patients. Bivariate analysis revealed comparatively reduced statin use among patients without other cardiovascular risk factors including hypertension (63% vs. 39.3%; P antiplatelet therapy use was associated with CAD and/or prior CABG/PCI (1.11 [1.04-1.17]; P = 0.0015) and prior peripheral revascularization (1.07 [1.01-1.13]; P = 0.03). Patients with symptomatic PAD, but without an antecedent cardiovascular history, are less likely to be optimally managed with statins and antiplatelet therapy preoperatively.

    Full Text Available Endovascular procedures for the management of the superficial femoral (SFA and popliteal artery disease are increasingly common. Over the past decade, several stent technologies have been established which may offer new options for improved clinical outcomes. This paper reviews the current evidence for SFA and popliteal artery angioplasty and stenting, with a focus on randomized trials and registries of nitinol self-expanding stents, drug-eluting stents, dug-coated balloons, and covered stent-grafts. We also highlight the limitations of the currently available data and the future routes in peripheral arterial disease (PAD stent and balloon technology.

    Background The Syntax score was recently developed as a comprehensive, angiographic tool grading the complexity of coronary artery disease (CAD). It aims to assist in patient selection and risk stratification of patients with extensive CAD undergoing revascularization. However, the prognostic value of the Syntax score in patients undergoing percutaneous coronary intervention (PCl) has not been validated. The aim of this study was to evaluate its role in predicting long-term incidences of major adverse cardiac and cerebrovascular events (MACCE) in patients undergoing PCl for 3-vessel disease.Methods Two hundred and three consecutive patients with de novo 3-vessel CAD undergoing PCI with sirolimus-eluting stents were studied. Their angiograms were scored according to the Syntax score. The patients were divided into tertiles according to the Syntax score: lowest Syntax score tertile (Syntax score ≤22), intermediate Syntax score tertile (Syntax score of 23 to 32), and the highest Syntax score tertile (Syntax score ≥33). During the 1-year follow-up, the MACCE-free survival curves were estimated by the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard regression analyses were performed to evaluate the relation between the Syntax score and the incidence of MACCE. Performance of the Syntax score was studied with respect to predicting the rate of MACCE by receiver operator characteristic (ROC) curves with an area under the curve.Results The overall Syntax score ranged from 6 to 66 with mean ± standard deviation of 27.9±12.6 and a median of 26.At 1 year, the Syntax score significantly predicted the risk of MACCE (HR 1.07/U increase, 95% Cl 1.04 to 1.11, P<0.001). The rate of MACCE was significantly increased among patients in the highest Syntax score tertile (17.9%) as compared with those with the lowest Syntax score tertile (1.4%, P <0.001) or intermediate Syntax score tertile (6.2%,P=0.041).

    Full Text Available Critical limb ischemia (CLI represents the most severe form of peripheral arterial disease (PAD and frequently occurs in medically frail patients. CLI patients frequently exhibit multi-segmental PAD commonly including the tibial arterial segment. Endovascular therapy has been established as first-line revascularization strategy for most CLI patients. Restenosis was reported to occur in up to more than two thirds of CLI patients undergoing angioplasty of complex tibial arterial obstructions. Nevertheless, favourable clinical outcomes were observed for infrapopopliteal angioplasty when compared with bypass surgery despite higher patency rates for the latter. Based on these observations, infrapopliteal patency was considered to be only of secondary importance upon clinical outcomes in CLI patients. In contrast to these earlier observations, however, recent findings from two randomized clinical trials indicate that infrapopliteal patency does impact on clinical outcomes in CLI patients. Purpose of the present manuscript is to provide a critical reappraisal of the present literature on the clinical importance of tibial arterial patency in CLI patients undergoing endovascular revascularization and to discuss utility and limitations of currently available anti-restenosis technologies.

    Individuals who are diagnosed with end-stage renal disease (ESRD) undergo major changes in lifestyle. The present cross-sectional study was conducted to identify the relationship between patients who undergo hemodialysis (HD) and their performance status, and how it is influenced by the presence of the level of depression and anxiety. A total of 50 patients were recruited from HD centers in and around Chennai. The patients were screened using the General Health Questionnaire to screen for co-morbid psychiatric conditions. The patients were assessed for depression and anxiety, and their performance status was assessed using Beck's Depression Inventory, Beck's Anxiety Inventory, and Karnofsky Performance Status. The study findings indicate that there is a positive correlation between anxiety and depression in ESRD patients. The findings also indicated that depression and anxiety are positively correlated with the performance status of ESRD patients. The duration on, as well as the frequency of dialysis, also correlated with the performance status of ESRD patients. It can be concluded that anxiety and depression are prevalent among ESRD patients and that they interfere with the performance status; additionally, duration on dialysis also interferes with performance status. Addressing depression and anxiety can help in enhancing the patient's performance status.

    Relatively high circulating levels of soluble tumor necrosis factor (TNF) receptors (TNFRs: TNFR1, TNFR2) have been associated with not only progression to end-stage renal disease but also mortality in patients with diabetes. It remains unknown whether elevated TNFR levels in haemodialysis patients are associated with mortality. We studied 319 patients receiving maintenance haemodialysis who were followed for a median of 53 months. Circulating markers of TNF pathway (TNFα and TNFRs) were measured with immunoassay. Strong positive correlations between TNFR1 and TNFR2 were observed (r = 0.81, P risk of cardiovascular and/or all-cause mortality independent of all relevant covariates in patients undergoing haemodialysis.

    Vedolizumab was recently approved by the Food and Drug Administration for the treatment of moderate to severe ulcerative colitis [UC] and Crohn's disease [CD]. No study to date has examined the rate of postoperative infectious complications among patients who received vedolizumab in the perioperative period. We sought to determine the 30-day postoperative infectious complication rate among inflammatory bowel disease [IBD] patients who received vedolizumab within 12 weeks of an abdominal operation as compared to patients who received tumour necrosis factor α [TNFα] inhibitors or no biological therapy. A retrospective chart review between May 1, 2014 and December 31, 2015 of adult IBD patients who underwent an abdominal operation was performed. The study cohort comprised patients who received vedolizumab within 12 weeks of their abdominal operation and the control cohorts were patients who received TNFα inhibitors or no biological therapy. In total, 94 patients received vedolizumab within 12 weeks of an abdominal operation. Fifty experienced postoperative complications [53%], 35 of which were surgical site infections [SSIs] [36%]. The vedolizumab group experienced significantly higher rates of any postoperative infection [53% vs 33% anti-TNF and 28% non-biologics; poperation experienced a 30-day postoperative SSI, significantly higher than patients receiving TNFα inhibitors or no biological therapy. Vedolizumab within 12 weeks of surgery remained the only predictor of 30-day postoperative SSI on multivariate analysis. Copyright © 2016 European Crohn’s and Colitis Organisation (ECCO).

    People with Parkinson's disease (PD) are at higher risk of malnutrition due to PD symptoms and pharmacotherapy side effects. When pharmacotherapy is no longer effective for symptom control, deep-brain stimulation (DBS) surgery may be considered. The aim of this study was to assess the nutritional status of people with PD who may be at higher risk of malnutrition related to unsatisfactory symptom management with optimised medical therapy. This was an observational study using a convenience sample. Participants were seen during their hospital admission for their deep brain stimulation surgery. People with PD scheduled for DBS surgery were recruited from a Brisbane neurological clinic (n=15). The Patient-Generated Subjective Global Assessment (PG-SGA), weight, height and body composition were assessed to determine nutritional status. Six participants (40%) were classified as moderately malnourished (SGA-B). Eight participants (53%) reported previous unintentional weight loss (average loss of 13%). On average, participants classified as well-nourished (SGA-A) were younger, had shorter disease durations, lower PG-SGA scores, higher body mass (BMI) and fat free mass indices (FFMI) when compared to malnourished participants (SGA-B). Five participants had previously received dietetic advice but only one in relation to unintentional weight loss. Malnutrition remains unrecognised and untreated in this group despite unintentional weight loss and presence of nutrition impact symptoms. Improving nutritional status prior to surgery may improve surgical outcomes.

    Chronic obstructive pulmonary disease (COPD) is considered a worldwide major public health problem. Weight loss, muscle and fat mass depletion are common nutritional problems in COPD patients and are determinant factors in pulmonary function, health status, disability and mortality. We aimed to assess the relationships between nutritional status and perception of dyspnoea, pulmonary function tests (PFT), exercise capacity and health-related quality of life (HRQoL) using the subjective global assessment (SGA) in COPD patients who were referred for pulmonary rehabilitation programme. A total of 163 patients with stable COPD who are candidates for outpatient pulmonary rehabilitation programme were included in this study. Nutritional status for all patients was assessed by SGA. Association of SGA scores (A, B and C) and anthropometric measurements, PFT, dyspnoea scales (Medical Research Council and resting BORG scale), HRQoL (St. George Respiratory Questionnaire and Chronic Respiratory Diseases Questionnaire) and exercise testing (shuttle walking test) were studied for statistical significance. Based on SGA, 9.2% of patients were severely malnourished (SGA-C). There were significant decreases in forced expiratory volume in the first second (FEV1 ) (P = 0.009), Medical Research Council scales (P nutritional status and determining any requirement for nutritional supplement is an important component of comprehensive pulmonary rehabilitation programme. SGA is an easy and practical method to assess nutritional status in pulmonary rehabilitation candidate patients with stable COPD. © 2013 The Authors.

    The effect of proctocolectomy and small bowel resection on working capacity has not been assessed objectively in previous research. Twenty-nine patients with Crohn's disease were investigated with cycle ergometry and a questionnaire, following proctocolectomy with and without small bowel resection. Maximal exercise load is known to correspond well with working capacity, particularly when account is taken of body composition and metabolic variables. Maximal exercise load was reduced marginally (by 9 per cent) in patients without small bowel resection and by 22 per cent in patients with moderate small bowel resection (15-30 per cent resection). Patients with extensive bowel resection (more than 50 per cent) had a 40 per cent reduction in the maximal exercise load. This reduction in maximal exercise load was greater than predicted when accounting for reduction in muscle mass. All patients had a normal oxygen uptake including resting energy expenditure. Urinary sodium and magnesium excretion was low in the group with moderate bowel resection, whereas the extensively resected patients were malnourished and had a reduced body cell mass. The authors conclude that the significantly reduced working capacity was of multifactorial origin secondary to malabsorption. However, the patients seemed unaware of the degree of their diminished working capacity. This reduced capacity makes it unlikely that they would be able to perform any labour involving high energy consumption at the level of 500-700 W, and this inability was reflected by a high rate of unemployment among the patients.

    Previously we discovered that routine periodic fasting was associated with a lower prevalence of coronary artery disease (CAD). Other studies have shown that fasting increases longevity in animals. A hypothesis-generating analysis suggested that fasting may also associate with diabetes. This study prospectively tested whether routine periodic fasting is associated with diabetes mellitus (DM). Patients (n = 200) undergoing coronary angiography were surveyed for routine fasting behavior before their procedure. DM diagnosis was based on physician reports of current and historical clinical and medication data. Secondary end points included CAD (physician reported for ≥ 1 lesion of ≥ 70% stenosis), glucose, and body mass index (BMI). Meta-analyses were performed by evaluation of these patients and 448 patients from a previous study. DM was present in 10.3% of patients who fasted routinely and 22.0% of those who do not fast (odds ratio [OR] 0.41, 95% confidence interval [CI] 0.17 to 0.99, p = 0.042). CAD was found in 63.2% of fasting and 75.0% of nonfasting patients (OR 0.42, CI 0.21 to 0.84, p = 0.014), and in nondiabetics this CAD association was similar (OR 0.38, CI 0.16 to 0.89, p = 0.025). Meta-analysis showed modest differences for fasters versus nonfasters in glucose concentrations (108 ± 36 vs 115 ± 46 mg/dl, p = 0.047) and BMI (27.9 ± 5.3 vs 29.0 ± 5.8 kg/m(2), p = 0.044). In conclusion, prospective hypothesis testing showed that routine periodic fasting was associated with a lower prevalence of DM in patients undergoing coronary angiography. A reported fasting association with a lower CAD risk was also validated and fasting associations with lower glucose and BMI were found. Copyright © 2012 Elsevier Inc. All rights reserved.

    To validate two previously presented models containing risk factors to identify patients with estimated glomerular filtration rate (eGFR) <60 ml/min/1.73 m{sup 2} or eGFR <45 ml/min/1.73 m{sup 2}. In random patients undergoing intravenous contrast-enhanced computed tomography (CECT) the following risk factors were assessed: history of urological/nephrological disease, hypertension, diabetes mellitus, anaemia, congestive heart failure, other cardiovascular disease or multiple myeloma or Waldenstroem disease. Data on kidney function, age, gender and type and indication of CECT were also registered. We studied two models: model A - diabetes mellitus, history of urological/nephrological disease, cardiovascular disease, hypertension; model B - diabetes mellitus, history of urological/nephrological disease, age >75 years and congestive heart failure. For each model, associations with eGFR <60 ml/min/1.73 m{sup 2} or eGFR <45 ml/min/1.73 m{sup 2} was studied. A total of 1,001 patients, mean age 60.36 years were included. In total, 92 (9.2 %) patients had an eGFR <60 ml/min/1.73 m{sup 2} and 11 (1.1 %) patients an eGFR <45 ml/min/1.73 m{sup 2}. Model A detected 543 patients: 81 with eGFR <60 ml/min/1.73 m{sup 2} (missing 11) and all 11 with eGFR <45 ml/min/1.73 m{sup 2}. Model B detected 420 patients: 70 (missing 22) with eGFR <60 ml/min/1.73 m{sup 2} and all 11 with eGFR <45 ml/min/1.73 m{sup 2}. Associations were significant (p < 0.05). Model B resulted in the lowest superfluous eGFR measurements while detecting all patients with eGFR <45 ml/min/1.73 m{sup 2} and nearly all with eGFR <60 ml/min/1.73 m{sup 2}. (orig.)

    The “reverse dipping” blood pressure (BP) pattern has been studied among the general population and in individuals suffering from hypertension. However, the prognosis of this pattern in chronic kidney disease (CKD) patients is not known. We monitored BP throughout the day and followed health outcomes in 588 CKD patients admitted to our hospital. Time to all-cause mortality, cardiovascular mortality, renal events and cardiovascular events was recorded. Multivariate-adjusted Cox regression analyses were carried out to detect the prognostic value of a reverse dipping BP pattern. Prevalence of a “dipper”, “non-dipper” and “reverse dippers” was 34.69%, 43.54% and 18.03%, respectively. Patients with a reverse dipping pattern had a higher prevalence of total mortality, cardiovascular mortality, renal events and cardiovascular events than patients with a dipping pattern (P < 0.025). Multivariate-adjusted Cox regression analyses showed that reverse dippers (versus dippers) were associated with a higher risk of total mortality (hazard ratio [HR], 5.08; 95% confidence interval [CI], 1.79~14.47), cardiovascular mortality (4.17; 1.25~13.88), renal events (3.00; 1.59~5.65) and cardiovascular events (4.12; 1.78~9.51) even after adjustment by 24-h systolic BP. These data suggest that a reverse dipping BP pattern, independent of 24-h levels of systolic BP, has prognostic value in CKD patients not undergoing dialysis. PMID:27713498

    Full Text Available Background. Acute kidney injury (AKI is a common complication of cardiac surgery but its long-term consequences, in patients with chronic kidney disease (CKD, are not known. Methods. We compared the long-term prognoses of CKD patients who developed (n=23 and did not develop (n=35 AKI during the period of hospitalization after undergoing coronary artery bypass graft (CABG. Fifty-eight patients who survived (69.6±8.4 years old, 72% males, 83% Whites, 52% diabetics, baseline GFR: 46±16 mL/min were followed up for 47.8±16.4 months and treated for secondary prevention of events. Results. There were 6 deaths, 4 in the AKI+ and 2 in the AKI− group (Log-rank = 0.218, two attributed to CV causes. At the end of the study, renal function was similar in the two groups. One AKI− patient was started on dialysis. Only 4 patients had an increase in serum creatinine ≥ 0.5 mg/dL during follow-up. Conclusion. CKD patients developing AKI that survived the early perioperative period of coronary intervention present good renal and nonrenal long-term prognosis, compared to patients who did not develop AKI.

    Full Text Available Abstract Background Studies in patients with low HDL have suggested that impaired cellular cholesterol efflux is a heritable phenotype increasing atherosclerosis risk. Less is known about the association of macrophage cholesterol efflux with lipid profiles and CAD risk in normolipidemic subjects. We have therefore measured macrophage cholesterol efflux in142 normolipidemic subjects undergoing coronary angiography. Methods Monocytes isolated from blood samples of patients scheduled for cardiac catheterization were differentiated into macrophages over seven days. Isotopic cholesterol efflux to exogenously added apolipoprotein A-I and HDL2 was measured. Quantitative cholesterol efflux from macrophages was correlated with lipoprotein subclass distribution in plasma from the same individuals measured by NMR-spectroscopy of lipids and with the extent of coronary artery disease seen on coronary angiography. Results Macrophage cholesterol efflux was positively correlated with particle concentration of smaller HDL and LDL particles but not with total plasma concentrations of HDL or LDL-cholesterol. We observed an inverse relationship between macrophage cholesterol efflux and the concntration of larger and triglyceride rich particles (VLDL, chylomicrons. Subjects with significant stenosis on coronary angiography had lower cholesterol efflux from macrophages compared to individuals without significant stenosis (adjusted p = 0.02. Conclusion Macrophage cholesterol efflux is inversely correlated with lipoprotein particle size and risk of CAD.

    While the assessment of β-D-glucan (BDG) levels in adults improves the early diagnosis of invasive fungal disease (IFD), data on BDG levels in children are limited. We therefore assessed in a prospective cohort study the value of serial BDG screening for early detection of IFD in children undergoing allogeneic hematopoietic stem cell transplantation (HSCT). IFD was defined according to the revised European Organization for Research and Treatment of Cancer/Mycosis Study Group (EORTC/MSG) criteria, with the necessary modification that BDG was not included as a microbiological criterion. For the analysis, a total of 702 serum samples were obtained in 34 pediatric HSCT recipients. Proven IFD occurred in two patients (fusariosis and Candida sepsis, respectively), and probable invasive aspergillosis was diagnosed in four patients. Analyses including different cutoff values for BDG levels and different definitions of the onset of IFD demonstrated that the BDG assay has a relatively high sensitivity and good negative predictive value, whereas the positive predictive value has major limitations (screening in pediatric HSCT recipients has a low positive predictive value and is therefore of limited usefulness.

    Full Text Available BACKGROUND The world is facing a global epidemic of Chronic Kidney Disease (CKD, a major threat to health in general because of an increasing incidence, high cost of treatment and poor outcome associated with various adverse events and comorbidities. Although improved control of hypertension is known to attenuate progression of Chronic Kidney Disease (CKD, a little is known about the adequacy of treatment of hypertension in patients with CKD in India. AIM To analyse the utilisation pattern of anti-hypertensive agents in patients with Chronic Kidney Disease in a tertiary care teaching Hospital. MATERIAL AND METHODS A descriptive prospective study was conducted in the Department of Nephrology, S. C. B. Medical College and Hospital, Cuttack, for a period of 6 months from 1st January 2015 to 30th June 2015. Relevant patient information, data regarding AntiHypertensive Drugs Utilization pattern entered in a preformed proforma in Microsoft Excel sheet for compilation and subjected to statistical analysis. RESULTS Total 100 case records were analysed. Mean age was 55.37±13.41 years. Male-female ratio was 2.7. Maximum number of patients were from age group 51-60 years (43% followed by age group 41-50 years (29%. All the patients (100% were hypertensives, among which 42% patients of the study population were diabetic with hypertension and rest of the patients (58% were non-diabetic with hypertension. Routinely prescribed anti-hypertensives are CCB, β blockers, diuretics, α blockers, ACEI and centrally acting sympatholytics. Among them, Calcium Channel Blockers (32.47% were most frequently used followed by β Blockers (24.78%, Diuretics (23.50%, Centrally Acting Sympatholytics (10.25%, α Blockers (7.69% and ACE Inhibitors (1.28%. Hypertension in CKD patients was very difficult to manage. Approximately, two-third of the patients (66% had BP >140/90 mmHg with anti-hypertensive therapy.

    Lanthanum carbonate is a non-calcium-based phosphate binder for hyperphosphatemia in patients with chronic kidney disease (CKD). The efficacy and safety of lanthanum carbonate (LaC) on hyperphosphatemia in patients has been well documented in clinical trials in Western countries and recent relatively short-term clinical trials in Japan. Evidence supporting its safety and efficacy in Japanese patients for longer-term treatment is now desired for clinical practice. A non-controlled, open-label, multicenter, one year study of LaC to assess safety and its effect on the levels of serum phosphate, serum calcium and parathyroid hormone was performed with Japanese dialysis patients. Lanthanum carbonate was administered to patients at variable doses for a period of 46-52 weeks. Evaluation of the safety and efficacy of LaC in reducing serum phosphate was performed, in addition to extensive and systematic monitoring of the laboratory parameters related to bone turnover and cardiac health. A significant reduction in the serum phosphate level was demonstrated throughout the treatment period (P < 0.05), without any increase in the frequency or severity of drug-related adverse events such as vomiting, nausea, and stomach discomfort. There was no clinically relevant change in vital signs, or electrocardiograms for a period. The profiles for parathyroid hormone, bone alkaline phosphates, and osteocalcin were stable in the patients concomitantly treated with vitamin D. This study provides further evidence that the administration of LaC over a period of one year is safe and effective for the reduction of serum phosphate levels in CKD patients undergoing hemodialysis.

    This study aimed to (a) investigate whether atorvastatin reload protects against acute heart failure (AHF) in patients with stable coronary artery disease (CAD) undergoing noncardiac emergency surgery and decreases the incidence of major adverse cardiac events (MACE) during hospitalization and (b) elucidate its possible mechanism of action. In total, 500 patients with stable CAD before noncardiac emergency surgery were randomized either to the atorvastatin reload or to the placebo group. All patients received atorvastatin treatment postoperatively. The primary end point was the incidence of AHF during hospitalization, and the secondary end point was the incidence of MACE during hospitalization. Preoperative and 72 h postoperative changes in high-sensitivity C-reactive protein and interleukin-6 levels were compared between the two groups. AHF during hospitalization occurred in 5.2% of patients in the atorvastatin reload group and 11.2% in the placebo group (P=0.0225). MACE during hospitalization occurred in 2.4% of patients in the atorvastatin reload group and 8.0% in the placebo group (P=0.0088). According to multivariable analysis, atorvastatin reload conferred a 50% reduction in the risk of AHF during hospitalization (odds ratio, 0.50; 95% confidence interval, 0.2-0.8; P=0.005). The median decrease in the high-sensitivity C-reactive protein and interleukin-6 levels was significantly greater in the atorvastatin reload group (Pemergency surgery by decreasing the incidence of AHF and MACE during hospitalization. The mechanism of this protective effect may involve inhibition of inflammation.

    Ninety-six consecutive above-knee femoropopliteal bypasses, using polytetrafluoroethylene (PTFE) preferentially, were performed for limb-threatening ischaemia. Cumulative primary graft patency was 68 per cent, 49 per cent and 36 per cent and limb salvage 93 per cent, 85 per cent and 75 per cent at 1, 3 and 5 yr respectively. As a result of poor long term survival (51 per cent at 5 yr), and the healing of remedial lesions before graft occlusion, 68 patients (72 per cent) required no further intervention. Eighteen secondary bypasses were undertaken, 12 using ipsilateral saphenous vein. In this group of elderly patients with poor life expectancy, where a limited operation is desirable, the use of PTFE provided excellent limb salvage with low morbidity. Although we can no longer justify our continued use of PTFE in every case of critical ischaemia because of its inferior patency to autogenous vein, we continue to use it preferentially in patients whose lifespan is likely to be short and in cases where a remedial lesion is present.

    Purpose: This prospective study aims to present the overall success rate, safety and long-term outcome of vibrational angioplasty technique, in the treatment of chronic total femoropopliteal occlusions in our institute. Methods: Between October 2000 and December 2008, patients with chronic total femoropoliteal arterial occlusions, treated with vibrational angioplasty during the same session after a failed attempt with conventional recanalization technique, were included. Patient's follow up included serial ankle-brachial index measurements and arterial duplex ultrasound examinations at 1, 3, 6, 12, 24, 36 and 48 months. Results: Twenty-seven patients (16 males and 11 females) and twenty-eight lesions were included in our study. Twenty-five lesions (89.3%) were successfully recanalized. Pain relief was noticed in twenty-one cases. From ten lesions with tissue loss (ulcer or gangrene) in successfully recanalized occlusions, six healed without major, or minor amputation. One non-healing amputation stump was healed after recanalization, without further complications. Four limbs underwent amputation (one minor and three major) despite successful recanalization, however all had an excellent healing of the amputation stump without further complications. The Kaplan–Meier test demonstrated 90%, 85% and 70% amputation-free survival rate at 12, 24 and 36 months, respectively. No major or minor complications were encountered. Conclusions: Vibrational angioplasty is a safe, effective and durable endovascular technique for the treatment of chronic total occlusions in patients with limb ischemia that would be difficult to recanalize using conventional intraluminal techniques.

    The objective of the work is to study the clinical and haemodynamic evolution, over 1 year, in patients with femoropopliteal arterial pathology treated by means of atherectomy with the SilverHawk device. Materials and methods: Nineteen (19) patients were treated between December 2008 and May 2009, collecting data on sex, age, comorbidity and clinical degree, with prospective monitoring over 12 months of clinical symptoms, physical examination and ecodoppler, obtaining results on diameter and peak systolic velocity at different arterial levels. Results: Of the 19 patients, 14 were men and 5 women, with a mean age of 70 years, hypertensive (73%), diabetic (63%) and smokers (63%). Six (6) presented disabling claudication and 13 critical ischemia with advanced distal trophic lesions in 5. A good arteriographic result was obtained in 12 cases, a stent was placed on the superficial femoral artery in 5 due to suboptimal outcome. Contrast extravasation was observed in 2, with femoropopliteal bypass performed and one exclusion with endoprosthesis for repair. In the ecodoppler after 1, 3, 6 and 12 months, a progressive reduction in lumen diameter and peak intraarterial systolic velocity was observed, particularly on the distal superficial femoral artery. After one year, 7 patients (36.8%) were symptom-free, 5 (26.3%) presented mild or moderate intermittent claudication and 1 patient (5.3%) presented localised distal trophic lesion. Four (4) major amputations were performed, in 2 the knee was preserved, there were 3 thromboses due to the procedure, a secondary endovascular procedure was performed in one case and a femoropopliteal bypass in another, and there were 2 non procedure-related deaths. Discussion: atherectomy with SilverHawk achieves an improvement in clinical degree, with a good rate of extremity salvage in patients with critical ischemia. In the first year, the ecodoppler shows evolution of the arteriopathy, without this necessarily meaning a clinical worsening.

    Restenosis or re-occlusion after femoropopliteal angioplasty or stent implantation is the main limitation of endovascular treatment strategies for peripheral artery disease. Within the last years, balloon catheters with anti-proliferative drug coating on the balloon surface have shown to be associated with higher patency rates compared to plain balloon angioplasty. Thus, drug-coated balloons were gradually adopted in many interventional centres for the treatment of femoropopliteal obstructions. The current review summarises the existing evidence for drug-coated balloons in the infrainguinal vessels and their indication in special lesion cohorts.

    To explore the cost-effectiveness of using drug-eluting balloon (DEB) angioplasty for the treatment of femoropopliteal arterial lesions, which has been shown to significantly lower the rates of target lesion revascularization (TLR) compared with standard balloon angioplasty (BA). A simplified decision-analytic model based on TLR rates reported in the literature was applied to baseline and follow-up costs associated with in-hospital patient treatment during 1 year of follow-up. Costs were expressed in Swiss Francs (sFr) and calculated per 100 patients treated. Budgets were analyzed in the context of current SwissDRG reimbursement figures and calculated from two different perspectives: a general budget on total treatment costs (third-party healthcare payer) as well as a budget focusing on the physician/facility provider perspective. After 1 year, use of DEB was associated with substantially lower total inpatient treatment costs when compared with BA (sFr 861,916 vs. sFr 951,877) despite the need for a greater investment at baseline related to higher prices for DEBs. In the absence of dedicated reimbursement incentives, however, use of DEB was shown to be the financially less favorable treatment approach from the physician/facility provider perspective (12-month total earnings: sFr 179,238 vs. sFr 333,678). Use of DEBs may be cost-effective through prevention of TLR at 1 year of follow-up. The introduction of dedicated financial incentives aimed at improving DEB reimbursements may help lower total healthcare costs.

    Persons at risk for autosomal dominant neurodegenerative diseases provide the opportunity to efficiently test preventive interventions. Only a minority of such persons, however, choose to undergo revealing genetic testing, presenting a challenge to enrollment. Thirty-four preclinical Latinos (n = 26) and non-Latinos at risk for familial Alzheimer's disease (FAD) unaware of their genetic status were administered a questionnaire exploring their interest in undergoing revealing genetic testing at baseline and in the context of eligibility for four prevention trials of increasing invasiveness. Forty-four percent of subjects expressed a baseline interest in undergoing revealing testing which increased to 85% in order to be eligible for a study of an oral drug "felt to be very safe." If there were a 50% chance of receiving placebo, this number dropped to 62% (p = 0.02). Among those not interested in a study involving a 50% chance of receiving placebo, a range of 5% to 40% chance of receiving placebo was given as acceptable. For more invasive studies, living in the United States (as opposed to Mexico) positively influenced the likelihood of participating. Our data suggest that clinical trial designs in which persons must confront their genetic status prior to enrollment are feasible. Study designs to minimize the likelihood of being placed on placebo or provide the eventual administration of the drug through open-label extensions should be considered.

    On preliminary evaluation, the microTEE probe provided good quality images in very small infants who were not amenable for transesophageal echocardiographic evaluation so far. The probe could be used safely in small infants without complications. It appears to be a promising imaging modality in the perioperative assessment of young infants undergoing cardiac surgery, in whom intraoperative epicardial echocardiography is currently the only tool.

    Subintimal angioplasty is a common treatment choice for chronic total occlusions (CTO) in the iliac and femoropopliteal arteries. This article describes the technical aspects and early outcomes of two different re-entry devices and comparison with manual re-entry technique. A retrospective review of 61 patients (re-entry group) treated with Outback or Pioneer Plus catheters was carried out. A matched cohort of patients (n=62) who underwent lower extremity interventions without the use of re-entry devices (manual re-entry group) were also analyzed (overall 123 patients were analyzed). Procedural success, procedural durations, patency estimates, ankle-brachial indices, and complications were analyzed. Sixty-one patients underwent Outback or Pioneer Plus guided subintimal recanalization. After the procedure, ankle-brachial indices significantly increased in all patients during follow-up. Primary patency for the entire cohort was 83% in the first month. When the re-entry device group was compared with manual re-entry group, no difference was found with respect to success, complication, and patencies between the two groups during follow-up. However, procedure duration and the amount of contrast agent used was significantly decreased in re-entry groups (pCTO using re-entry devices for aortoiliac or femoropopliteal arteries is safe and effective. These devices shorten the procedure time, the re-entry time, reduce radiation risk, and reduce the amount of contrast agent employed.

    Due to intimal hyperplasia instent reobstruction in the femoropopliteal arterial segment is still an unsolved problem. Different techniques have been discussed in case of reintervention to guarantee longlasting patency rate. We conducted a randomized, controlled, pilot trial comparing Silverhawk atherectomy with percutaneous transluminal angioplasty (PTA) in patients with a first instent reobstruction in the femoropopliteal arterial segment, to evaluate intima media thickness (IMT) within the treated segment, as a parameter of recurrence of intimal hyperplasia. In a total 19 patients were included: 9 patients in the atherectomy device and 10 patients in the PTA arm. IMT within the treated segment was statistically significantly elevated in all patients treated with the Silverhawk device versus the patients treated with PTA. The obvious differentiation in elevation of IMT in nonfavor for patients treated with the Silverhawk device started at month 2 (max IMT SH 0.178 mm vs. IMT PTA 0.1 mm, p = 0.001) with a spike at month 5 (max IMT SH 0.206 mm vs. IMT PTA 0.145 mm, p = 0.003) and a decline once again at month 6 (max IMT SH 0.177 mm vs. IMT PTA 0.121 mm, p = 0.02). The values for mean IMT performed the same way. Although Silverhawk atherectomy provides good results at first sight, in the midterm follow-up of treatment of first instent restenosis it did not perform better than PTA as it showed elevated reoccurrence of intimal media hyperplasia.

    Cancer patients, in general, suffer from anorexia hence diminished nutritional intake. In a prospective observational study, we investigated the impact of recent energy and protein intake on cancer-related fatigue and 6-month mortality in patients undergoing chemotherapy. Recent protein and energy intake was assessed by 24-h recall in 285 patients. Cancer-related fatigue was determined by Brief Fatigue Inventory, and fat free mass index (FFMI) was assessed with bioelectrical impedance analysis. Symptoms with the validated German version of European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire (30 questions) and 6-month mortality was documented. Risk factors of cancer-related fatigue and predictors of mortality were investigated with logistic regression analysis and stepwise Cox regression analysis, respectively. Low protein intake (protein intake emerged as the strongest contributor to cancer-related fatigue followed by nausea/vomiting, insomnia, and age. Reduced protein intake, male sex, number of comorbidities, and FFMI were identified as significant predictors for increased 6-month mortality. In conclusion, a low recent protein intake assessed by 24-h recall is associated with a more than twofold higher risk of cancer-related fatigue and 6-month mortality. Every effort should be taken to assess and guarantee proper nutritional intake in patients undergoing chemotherapy.

    The aim of this study was to evaluate microbiological findings and aMMP-8 level of peri-implant mucositis (M) and peri-implantitis (P) in patients undergoing supportive implant therapy (SIT). Eighty-nine patients with 171 implants were included. The case definitions were as follows: M: PPD ≥4mm, BOP; P: PPD≥4mm, BOP, radiographic bone loss ≥3.5mm. Samples of peri-implant sulcular fluid (PISF) were taken from all peri-implant pockets at each implant to detect periodontal pathogens using PCR and aMMP-8 level with ELISA. Only Treponema denticola (Td) and Prevotella intermedia (Pi) showed significantly higher prevalence in P (healthy implants [HI]: Td=27%, Pi=17%; M: Td=26%, Pi=15%; P: Td and Pi=50%; P<0.05). The mean aMMP-8 level at implant sites did not show any significant difference (P=0.05) among HI (5.2±8.1), M (9.9±19.0), and P (4.9±7.7). Microbiological findings and aMMP-8 levels are not reliable criteria to distinguish between HI, M, and P in patients undergoing SIT.

    This study was carried out on 48 patients with ESRD undergoing hemodialysis treatment (29 males and 19 females, mean age 50.8 years) and renal transplantation (15 females and 33 males, mean age 42.2 years). The results were compared with a group of 44 healthy persons (23 females and 21 males, mean age 49.5 years). The aim of our investigation was to examine the content of fluoride in the mixed unstimulated saliva of the patients undergoing renal replacement therapy and in the control group of healthy persons. We studied the influence of hemodialysis on saliva fluoride levels. Saliva samples were collected by the spitting method according to Navazesh. Samples were collected before and after hemodialysis session and once in graft recipients and controls. Fluoride concentrations were determined with an Orion fluoroselective electrode model 96-09. The fluoride level in healthy persons was 4.92 +/- 2.30 micromol/L. Before hemodialysis, the mean fluoride level was 9.63 +/- 3.90 micromol/L and decreased significantly to 7.52 +/- 2.71 micromol/L after hemodialysis (p < 0.0001). Saliva content of fluorides in patients before and after hemodialysis was significantly higher than in healthy subjects and kidney graft recipients (p < 0.0001). There was no significant difference in fluoride concentration between patients after kidney transplantation and controls. The results suggest the need for individual fluoride supplementation in chronically hemodialysed patients.

    Full Text Available Background Nonalcoholic fatty liver disease (NAFLD is one of the most common causes of chronic liver disease including simple steatosis to nonalcoholic steatohepatitis (NASH. NASH could progress to cirrhosis and liver cancer. The prevalence of NAFLD is increasing by increasing the prevalence of obesity. Objectives This study was designed to determine the prevalence of NASH in morbidly obese patients undergoing sleeve bariatric surgery and its correlation with other comorbidities. Patients and Methods In this analytical cross-sectional study, 114 morbidly obese patients undergoing sleeve gastrectomy were selected. Liver ultrasonography was performed for all patients before surgery and NAFLD existence and its grade was determined by hyperechoic texture and fatty infiltration. The liver enzymes and lipid profile were also measured. Prevalence of NAFLD in these patients and its correlation with other comorbid conditions (e.g. diabetes mellitus, hyperlipidemia, hypertension, hypothyroidism and ischemic heart disease were evaluated by SPSS software version 18. Results One hundred fourteen patients with a mean age of 33.96 ± 9.92 years and mean BMI of 43.61 ± 5.77 kg/m2 were enrolled (48 males and 66 females. The prevalence of NAFLD was 16.7%. NAFLD existence was associated with systolic blood pressure, hyperlipidemia, hemoglobin, hematocrit, triglyceride, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and potassium (P < 0.05. Conclusions According to high prevalence of NAFLD in morbidly obese patients undergoing sleeve gastrectomy in Iran, we suggest using gold standard diagnostic method to determine the exact NAFLD prevalence and evaluation of impact of sleeve surgery on NAFLD in short and long term follow-up periods.

    Study of valves is inseparable from that of the main veins in which they are located. While a modal femoro-popliteal system, satellite to the arterial system, is by far the commonest, major variations are seen in approximately 10% of cases. Each main collecting vein has its specificity, according to its width, the course which it follows and whether or not there is a satellite wide calibre artery. Additional features include the chief affluents which its receives, wavering of its course, the supple or rigid perivascular environment and the proximity of large muscle masses. All these features play a role in the quality of drainage, in particular during exercise, and in anti-reflux function. In practice, variations come down to two broad possibilities: the single collector, sometimes made up of several different embryological segments, resulting in a hybrid vessel and an aberrant course, either axial, satellite to the sciatic nerve, or profunda femoris, satellite to the shaft of the femur. Doubling (bifid or by bifurcation) opens up an additional channel, either parallel or divergent, which considerably modifies the conditions of venous return. A lesion affecting one branch only, e.g. a solitary thrombus, may have no clinical manifestations and marking if collectors during imaging. The topography of the valves of the main veins tends to be fairly fixed. They are preferentially located proximal to the main confluents, to winding parts of the course of the vessel, or at certain hemodynamic levels which vary little from one individual to another. An attempt is made at nomenclature, classification and topography. The chief feature, the terminal valve of the lower limb, is located most often at the femoral ring. It alone is capable of opposing the long cavo-iliac reflux caused by effort. Analysis of retrograde phlebography films with caval occlusion shows that reflux is not directly exerted on the valve. The point of interruption is high, in the terminal portion of the

To promote better treatment outcome, as well as economic benefit it is very important to find out patients with simultaneous occurrence of both aortic and arterial aneurysms. The aim of this prospective study was to determine the frequency and factors affecting femoropopliteal (F-P segment aneurysms appearance in patients with abdominal aortic aneurysms (AAA. Methods. This study included 70 patients who had underwent elective or urgent surgery of AAA from January 1, 2006 to December 31, 2007. After ultrasonographic examination of F-P segment, all the patients were divided into two groups - those with adjunctive F-P segment aneurysm (n = 20 and the group of 50 patients with no adjunctive F-P segment aneurysm. In both groups demographic characteristics (gender, age, risk factors (diabetes mellitus, elevated serum levels of cholesterol and triglycerides, arterial hypertension, smoking, obesity and cardiovascular comorbidity (cerebrovascular desease, ischemic heart desease were investigated.

    Objectives To assess the impact on stent implantation rate and mid-term outcomes of prolonged high pressure angioplasty of femoropopliteal lesions. Methods We retrospectively enrolled 620 consecutive patients from January 2011 to December 2011 (75.6 ±12.3 years, 355 males, 76.5%in Rutherford class 5-6), referred for critical limb ischemia and submitted to prolonged high-pressure angioplasty of femoropopliteal lesions. The definition of prolonged high-pressure angioplasty includes dilation to at least 18 atm for at least 120 s. Proce-dural data, and clinical and instrumental follow-up were analyzed to assess stent implantation rate and mid-term outcomes. Results The preferred approach was ipsilateral femoral antegrade in 433/620 patients (69.7%) and contralateral cross-over in 164/620 (26.4%) and pop-liteal retrograde+femoral antegrade in 23/620 (3.7%). Techniques included subintimal angioplasty in 427/620 patients (68.8%) and endolu-minal angioplasty in 193/620 patients (31.2%). The prolonged high pressure balloon angioplasty procedure was successful in 86.2%(minor intra-procedural complications rate 15.7%), stent implantation was performed in 74 patients (11.9%), with a significant improvement of ankle-brachial index (0.29 ±0.6 vs. 0.88 ±0.3, P<00.1) and Rutherford class (5.3 ±0.8 vs. 0.7 ±1.9, P<0.01), a primary patency rate of 86.7%, restenosis of 18.6%on Doppler ultrasound and a target lesion revascularization of 14.8%at a mean follow-up of 18.1 ±6.4 months (range 1-24 months). Secondary patency rate was 87.7%. Conclusions Prolonged high pressure angioplasty of femoropopliteal lesions appears to be safe and effective allowing for an acceptable patency and restenosis rates on mid-term.

    Among end-stage renal disease (ESRD) patients, cardiovascular disease is a common comorbidity and one of most important factors affecting clinical prognosis. Calcium deposition has been reported to correlate with plasma phosphate. Icodextrin (Ico)-based peritoneal dialysis (PD) has many advantages over glucose (Glu)-based PD. We aimed to identify factors that suppress arteriosclerosis and valvular disease in patients with ESRD and diabetes mellitus (DM) undergoing Ico-based PD. In this retrospective study, we evaluated the effects of Ico-based PD (n = 20) on phosphate elimination and cardiovascular disease progression in patients with ESRD andDM, and we compared the results with those for Glu-based PD (n = 20). Left ventricular mass index (LVMI) and aortic valve calcification (AVC) score were significantly decreased and daily phosphate elimination was significantly increased in the Ico group compared with the Glu group. Furthermore, mean daily phosphate elimination was significantly and negatively correlated with the amelioration in LVMI and AVC score. Our study suggests that, compared with glucose, icodextrin has the ability to eliminate more phosphate from the body, indicating that phosphate elimination might potentially be a means of controlling cardiovascular disease in PD patients with DM.

    Patients with peripheral vascular disease (PVD) often have coronary artery disease (CAD) which means an increased risk during anesthesia. The prevalence of CAD is nearly 50% among such patients. Owing to claudication, diagnostic stress tests can rarely be performed in PVD patients. In order to evaluate the frequency of transient perioperative myocardial ischemia, Holter monitoring was performed in 30 consecutive PVD patients with ASA II-III and AVK scale (Fontaine) II-IV who were undergoing femoropopliteal bypass surgery. Patients who had left bundle branch block and left ventricular hypertrophy or were taking digitalis medication were excluded from Holter monitoring. The ST-segment analysis of the frequency modulated recordings (n = 19) revealed episodes of myocardial ischemia in 26% of the patients. Most (75%) of the episodes occurred preoperatively, and 25%, during or after the anesthesia or during preparation for it. Risk factors for CAD were more often found in patients with ST segment alterations than in patients without ST segment deviations, even though the preoperative antianginal medication administered was comparable in the two subgroups. It is concluded that in a considerable subset of PVD patients silent myocardial ischemia occurs, which can be related to the different perioperative intervals by means of ST segment analyses of Holter recordings. The ST segment may allow a better insight into the cardiac state of PVD patients. Further studies are necessary in larger populations to test our suspicion.

    Effective diagnostic tools for management of HIV disease progression in Sub-Saharan Africa is inadequate considering the endemic nature of the infection in the region. To elucidate the clinical implication of oxidative stress (measured as Malondialdehyde, MDA) as additional biomarker of HIV disease progression and its implication in HIV clinical management. A total of 250 individuals were recruited for the study. FACScan cytometry and spectrophotometric methods were employed in assessing T-lymphocytes (CD3, CD4, CD8) and MDA respectively. MDA concentration increased significantly (P < 0.05) in highly active antiretroviral therapy (HAART) subjects by 12.72% in category 1, 9.75% in III and in category II (4.63%) on comparison with non-HAART subjects. In subjects taking HAART, 22.2%, 56.3%, and 22.2% were found to be in category I, II and III, respectively, with a corresponding non-HAART values of 15.6%, 45.6% and 38.9%. However, Spearman's rank correlation (P < 0.001) statistics of MDA and HIV categories showed a negative correlation in all the categories (I, II and III). These findings suggest that MDA may be an additional clinical factor in assessing progression of HIV disease; however, necessary fortification of regimen with antioxidant may help reduce the high MDA concentration in the disease progression of the infection.

    The OLmesartan on the progression of coronary atherosclerosis: evaluation by IntraVascular UltraSound (OLIVUS) trial demonstrated that an angiotensin II receptor blocker, olmesartan, reduces the rate of coronary atheroma progression as evaluated by intravascular ultrasound in patients with stable angina pectoris undergoing percutaneous coronary intervention. This substudy examined the impact of olmesartan on serum biomarkers and the relationship between biomarker changes and atheroma progression. Patients in the OLIVUS trial (n = 247) were randomly assigned to a control group or the olmesartan group. A subgroup of these patients (n = 135, 55 %) was analyzed at baseline and at 14 months. Patients' characteristics and blood-pressure control were identical between the control group (n = 65) and the olmesartan group (n = 70), and also between the subpopulation and total population. The change in the level of high-sensitivity C-reactive protein (hs-CRP) (mg/l) and adiponectin (μg/ml) was significantly greater in the olmesartan group than in the control group (between-group differences: 0.5 and -0.7; 95 % confidence interval: 0.2-0.8 and -1.3 to -0.1; P = 0.001 and 0.02, respectively). Multiple regression analysis revealed that the nominal changes in total atheroma volume and percent atheroma volume were significantly associated with the nominal change in hs-CRP in the olmesartan group but not in the control group. Olmesartan reduced hs-CRP in patients with stable angina, and this correlated with the change in coronary atheroma.

    Background Stroke is a rare but serious adverse event associated with percutaneous coronary intervention (PCI). However, the relative risk of stroke between stable patients undergoing a direct PCI strategy and those undergoing an initial optimal medical therapy (OMT) strategy has not been established yet. This study sought to investigate if, in patients with stable coronary artery disease (SCAD), an initial strategy PCI is associated with a higher risk of stroke than a strategy based on OMT alone. Methods We performed a meta-analysis of 6 contemporary randomized control trials in which 5673 patients with SCAD were randomized to initial PCI or OMT. Only trials with stent utilization more than 50% were included. Study endpoint was the rate of stroke during follow up. Results Mean age of patients ranged from 60 to 65 years and stent utilization ranged from 72% to 100%. Rate of stroke was 2.0% at a weighted mean follow up of 55.3 months. On pooled analysis, the risk of stroke was similar between patients undergoing a PCI plus OMT and those receiving only OMT (2.2% vs. 1.8%, OR on fixed effect = 1.24 95%CI: 0.85–1.79). There was no heterogeneity among the studies (I2 = 0.0%, P = 0.15). On sensitivity analysis after removing each individual study the pooled effect estimate remains unchanged. Conclusions In patients with SCAD an initial strategy based on a direct PCI is not associated with an increased risk of stroke during long-term follow up compared to an initial strategy based on OMT alone.

    Purpose: In this retrospective study, we report on outcomes and prognostic factors for patients treated with stereotactic radiosurgery (SRS) for breast cancer brain metastases. Methods and Materials: We identified 132 consecutive patients with breast cancer who were treated with SRS for brain metastases from January 2000 through June 2010. We retrospectively reviewed records of the 51 patients with adequate follow-up data who received SRS as part of the initial management of their brain metastases. Overall survival (OS) and time to central nervous system (CNS) progression from the date of SRS were calculated using the Kaplan-Meier method. Prognostic factors were evaluated using the Cox proportional hazards model. Results: Triple negative subtype was associated with CNS progression on univariate analysis (hazard ratio [HR] = 5.0, p = 0.008). On multivariate analysis, triple negative subtype (HR = 8.6, p = 0.001), Luminal B subtype (HR = 4.3, p = 0.03), and omission of whole-brain radiation therapy (HR = 3.7, p = 0.02) were associated with CNS progression. With respect to OS, Karnofsky Performance Status (KPS) {<=} 80% (HR = 2.0, p = 0.04) and progressive extracranial disease (HR = 3.1, p = 0.002) were significant on univariate analysis; KPS {<=} 80% (HR = 4.1, p = 0.0004), progressive extracranial disease (HR = 6.4, p < 0.0001), and triple negative subtype (HR = 2.9, p = 0.04) were significant on multivariate analysis. Although median survival times were consistent with those predicted by the breast cancer-specific Graded Prognostic Assessment (Breast-GPA) score, the addition of extracranial disease status further separated patient outcomes. Conclusions: Tumor subtype is associated with risk of CNS progression after SRS for breast cancer brain metastases. In addition to tumor subtype and KPS, which are incorporated into the Breast-GPA, progressive extracranial disease may be an important prognostic factor for OS.

    To assess the subjective sleep quality and its relationship with the presence of psychiatric morbidity in the patients suffering from chronic kidney disease (CKD) and undergoing the procedure of hemodialysis (HD); and analyze the associated socio-demographic factors. Cross-sectional descriptive study. Nephrology Department, Military Hospital, Rawalpindi, from July to December 2016. Patients of CKD undergoing the HD were included in the final analysis. Quality of sleep was determined by using the Pittsburgh Sleep Quality Index (PSQI). Psychiatric morbidity was determined by the General Health Questionnaire 12 (GHQ-12). Relationship of education, BMI, gender, age, duration of dialysis, dialysis count per week, marital status, level of family income, psychiatric morbidity, occupation, biochemical markers (urea, creatinine, BUN, albumin, calcium, phosphorous and hemoglobin), tobacco smoking, and use of naswar was determined with the sleep quality. One hundred and forty patients were screened through the PSQI; 44 (31.4%) had good quality of sleep while 96 (68.6%) had poor sleep quality. Statistical analysis revealed that presence of psychiatric morbidity, increasing age, female gender, being unmarried, low family income, and low frequency of dialysis had significant association with the poor sleep quality. Poor sleep quality was highly prevalent among the patients of CKD receiving the hemodialysis. The patients with low family income, more age, and with two or less dialysis sessions per week should be screened thoroughly for the sleep problems. Presence of psychiatric morbidity emerged as an independent factor responsible for the poor sleep quality in our target population.

    Parkinson's disease (PD) is traditionally regarded as a neurodegenerative movement disorder, however, nigrostriatal dopaminergic degeneration is also thought to disrupt non-motor loops connecting basal ganglia to areas in frontal cortex involved in cognition and emotion processing. PD patients are impaired on tests of emotion recognition, but it is difficult to disentangle this deficit from the more general cognitive dysfunction that frequently accompanies disease progression. Testing for emotion recognition deficits early in the disease course, prior to cognitive decline, better assesses the sensitivity of these non-motor corticobasal ganglia-thalamocortical loops involved in emotion processing to early degenerative change in basal ganglia circuits. In addition, contrasting this with a group of healthy aging individuals demonstrates changes in emotion processing specific to the degeneration of basal ganglia circuitry in PD. Early PD patients (EPD) were recruited from a randomized clinical trial testing the safety and tolerability of deep brain stimulation (DBS) of the subthalamic nucleus (STN-DBS) in early-staged PD. EPD patients were previously randomized to receive optimal drug therapy only (ODT), or drug therapy plus STN-DBS (ODT + DBS). Matched healthy elderly controls (HEC) and young controls (HYC) also participated in this study. Participants completed two control tasks and three emotion recognition tests that varied in stimulus domain. EPD patients were impaired on all emotion recognition tasks compared to HEC. Neither therapy type (ODT or ODT + DBS) nor therapy state (ON/OFF) altered emotion recognition performance in this study. Finally, HEC were impaired on vocal emotion recognition relative to HYC, suggesting a decline related to healthy aging. This study supports the existence of impaired emotion recognition early in the PD course, implicating an early disruption of fronto-striatal loops mediating emotional function.

    Low cardiac output syndrome remains a serious complication, and accounts for substantial morbidity and mortality in the postoperative course of paediatric patients undergoing surgery for congenital heart disease. Standard prophylactic and therapeutic strategies for low cardiac output syndrome are based mainly on catecholamines, which are effective drugs, but have considerable side effects. Levosimendan, a calcium sensitiser, enhances the myocardial function by generating more energy-efficient myocardial contractility than achieved via adrenergic stimulation with catecholamines. Thus potentially, levosimendan is a beneficial alternative to standard medication for the prevention of low cardiac output syndrome in paediatric patients after open heart surgery. To review the efficacy and safety of the postoperative prophylactic use of levosimendan for the prevention of low cardiac output syndrome and mortality in paediatric patients undergoing surgery for congenital heart disease. We identified trials via systematic searches of CENTRAL, MEDLINE, Embase, and Web of Science, as well as clinical trial registries, in June 2016. Reference lists from primary studies and review articles were checked for additional references. We only included randomised controlled trials (RCT) in our analysis that compared prophylactic levosimendan with standard medication or placebo, in infants and children up to 18 years of age, who were undergoing surgery for congenital heart disease. Two review authors independently extracted data and assessed risk of bias according to a pre-defined protocol. We obtained additional information from all but one of the study authors of the included studies. We used the five GRADE considerations (study limitations, consistency of effect, imprecision, indirectness, and publication bias) to assess the quality of evidence from the studies that contributed data to the meta-analyses for the prespecified outcomes. We created a 'Summary of findings' table to

  7. Changes in GABA and Glutamate concentrations during Memory Tasks in Patients with Parkinson’s disease undergoing DBS Surgery

    2014-03-01

    Full Text Available Until now direct neurochemical measurements during memory tasks have not been accomplished in the human basal ganglia. It has been proposed, based on both functional imaging studies and psychometric testing in normal subjects and in patients with Parkinson’s disease (PD, that the basal ganglia is responsible for the performance of feedback-contingent implicit memory tasks. To measure neurotransmitters, we used in-vivo microdialysis during deep brain stimulator (DBS surgery. We show in the right subthalamic nucleus (STN of patients with PD a task-dependent change in the concentrations of glutamate and GABA during an implicit memory task relative to baseline, while no difference was found between declarative memory tasks. The five patients studied had a significant decrease in the percent concentration of GABA and glutamate during the performance of the Weather Prediction Task (WPT. We hypothesize, based on current models of basal ganglia function, that this decrease in the concentration is consistent with expected dysfunction in basal ganglia networks in patients with Parkinson’s disease.

    To evaluate the efficacy of various strategies for revascularization of chronic total occlusion of femoropopliteal arteries when the guide wire does not pass in an anterograde direction. Twenty-four patients with totally occluded femoropopliteal arteries (mean occlusion length 13.75 cm; range, 6-22 cm) were treated by using a retrograde approach and two novel catheters. After successful recanalization or reentry, balloon angioplasty followed by stent placement was performed to complete the revascularization. In 16 cases in which to cross the occlusion via intraluminal or subintimal route was failed, we used Frontrunner catheters in five cases and Outback catheters in 11 cases. In eight cases in which to reenter after subintimal passage of the guide wire was failed, we used Outback catheters. Successful recanalization was achieved intraluminally or subintimally in all cases. One perforation occurred during subintimal passage of the guide wire that was controlled by recanalization of another subintimal tract. There were no cases of distal thromboembolism or other complications. A retrograde approach and using the Frontrunner and Outback catheters are safe and effective for successful revascularization of chronic total occlusion of femoropopliteal arteries. In particular, they are useful when the initial antegrade attempts at recanalization have failed.

    This study assessed the usefulness of thallium stress testing as a predictor of perioperative cardiovascular risk in diabetic patients with end-stage renal disease undergoing cadaveric renal transplantation. Demographic factors influencing the exercise performance in these patients were also examined. The medical records of 189 consecutive patients with diabetic nephropathy who were evaluated for cadaveric renal transplantation were reviewed. Thallium stress testing was the initial examination of cardiovascular status in 141 patients. An adequate examination was one in which at least 70% of maximum heart rate was achieved. A thallium stress test was normal if there were no ST segment depressions on the electrocardiogram and no perfusion abnormalities on the thallium scan. Forty-four patients underwent cardiac catheterization as the initial evaluation (Group C) and four patients underwent transplantation without a formal cardiovascular evaluation (Group D). Sixty-four of the 141 patients undergoing thallium stress testing had an adequate and normal examination (Group A). The incidence of perioperative cardiac events in this group was 2%. Seventy-seven patients (Group B) had an abnormal (n = 41) or an inadequate (n = 36) thallium stress test and most (n = 61) then underwent coronary angiography. The use of beta-blockers was the only predictor of an abnormal or inadequate thallium stress test. Forty-three percent of patients with inadequate or abnormal thallium stress tests had significant coronary artery disease on cardiac catheterization. The perioperative risk of cardiac events was not different in Group A versus Groups B, C, and D combined. Survival of Group A and B patients was not different but was significantly longer than that of Group C patients.

    To develop and evaluate an individualized fluid therapy in the elderly patients with coronary heart disease undergoing gastrointestinal surgery. In this prospective study, 60 coronary heart disease patients undergoing gastrointestinal surgery were included in the First Affiliated Hospital of Xinjiang Medical University from March 2009 to March 2012. Patients were randomized into the intervention group and the control group with 30 patients in each group. Individualized fluid therapy was used during surgery and postoperative period in the ICU, which was determined based on target controlled fluid therapy according to cardiac index, stroke volume, and stroke volume variation. Traditional fluid therapy was used in the control group in the intraoperative and postoperative period. The two groups were compared in terms of postoperative hemodynamic parameters, total fluid volume, incidence of adverse cardiac events, and recovery of bowel function. Compared with the control group, mean arterial pressure was significantly increased at the commencement of the surgery. The cardiac index was significantly elevated during surgery and at the end of the surgery. Stroke volume was significantly increased after induction of anesthesia, during the surgery, and at the early stay of ICU period(all Pfluid volume, crystal usage, and urine were significantly less, while colloidal fluid use was significantly more in the intervention group as compared to the control group(all P0.05). In the intervention group, defecation time, time to first flatus, resumption of liquid intake, length of ICU stay and hospital stay were significantly less compared with the control group(Pfluid therapy can effectively decrease adverse cardiac events, improve postoperative gastrointestinal function, and reduce length of hospital stay.

    To assess which risk factors can be used to reduce superfluous estimated glomerular filtration rate (eGFR) measurements before intravenous contrast medium administration. In consecutive patients, all decreased eGFR risk factors were assessed: diabetes mellitus (DM), history of urologic/nephrologic disease (HUND), nephrotoxic medication, cardiovascular disease, hypertension, age > 60 years, anaemia, malignancy and multiple myeloma/M. Waldenstroem. We studied four models: (1) all risk factors, (2) DM, HUND, hypertension, age > 60 years; (3) DM, HUND, cardiovascular disease, hypertension; (4) DM, HUND, age > 75 years and congestive heart failure. For each model, association with eGFR < 60 ml/min/1.73 m{sup 2} or eGFR < 45 ml/min/1.73 m{sup 2} was studied. A total of 998 patients, mean age 59.94 years were included; 112 with eGFR < 60 ml/min/1.73 m{sup 2} and 30 with eGFR < 45 ml/min/1.73 m{sup 2}. Model 1 detected 816 patients: 108 with eGFR < 60 ml/min/1.73 m{sup 2} and all 30 with eGFR < 45 ml/min/1.73 m{sup 2}. Model 2 detected 745 patients: 108 with eGFR < 60 ml/min/1.73 m{sup 2} and all 30 with eGFR < 45 ml/min/1.73 m{sup 2}. Model 3 detected 622 patients: 100 with eGFR < 60 ml/min/1.73 m{sup 2} and all 30 with eGFR < 45 ml/min/1.73 m{sup 2}. Model 4 detected 440 patients: 86 with eGFR < 60 ml/min/1.73 m{sup 2} and all 30 with eGFR < 45 ml/min/1.73 m{sup 2}. Associations were significant (p < 0.001). Model 4 is most effective, resulting in the lowest proportion of superfluous eGFR measurements while detecting all patients with eGFR < 45 ml/min/1.73 m{sup 2} and most with eGFR < 60 ml/min/1.73 m{sup 2}.

    Full Text Available The study was supported by the grant of the President of the Russian Federation MK-2076.2012.6. In the current study, the authors evaluated the role of relationship to disease in cardiac patients undergoing vital threat in the formation of the prediction of their mental adaptation in the distant post-hospital period. Longitudinal study (in-hospital and one year after discharge included two groups: patients with urgent cardiac status (N=47, 36 men, 11 women, age 34 to 66 years and patients with atrial arrhythmias, passing minimally invasive surgery (N=41, 22 men, 19 women, age 41 to 69 years. In-hospital stage used interviews and tests, questionnaires, and post-hospital stage was conducted using a telephone interview. We found that patients with a history of life-threatening cardiac condition, are less concerned about the disease than patients expecting to be relatively safe after minimally invasive surgery. In the forecast of the emotional status of patients, the severity of anxiety and disturbance of interpersonal relationships in the hospital period play an important role. Predictor of adherence to medical recommendations for men is a high disease concern, and in women – greater emotional stability.

    Full Text Available A 38-year-old woman with acoustic neuroma associated with occupational interstitial lung disease (ILD was successfully managed for sitting position craniotomy using carefully titrated desflurane-based anaesthesia. The anaesthetic challenges included maintenance an adequate depth of anaesthesia, reducing perioperative airway events and ensuring smooth recovery. While dealing with ILD patient in sitting position, careful risk assessment is important because it will help us predict the course of the perioperative events. Balanced general anaesthesia using desflurane fulfilled the requirement of good depth and smooth recovery in this patient. Though there are reports of maintenance of anaesthesia with other inhalational agents, there are scanty reports of using desflurane in these cases.

    OBJECTIVES: The prenatal detection rate of congenital heart disease (CHD) is low compared with other fetal malformations. Our aim was to evaluate the prenatal detection of CHD in Eastern Denmark. METHODS: Fetuses and infants diagnosed with CHD in the period 01.01.2008-31.12.2010 were assessed...... regarding prenatal detection rate and accuracy, as well as correlation with nuchal translucency (NT) thickness. RESULTS: Out of 86 121 infants, 831 were born with CHD (0.96%). The prenatal detection rate of 'all CHD' was 21.3%, of 'Major CHD' 47.4%. Full agreement between prenatal and postnatal....../autopsy findings was found in 96% of prenatally detected diagnoses. An NT thickness >95(th) percentile was found in 15.0% fetuses with 'Major CHD'. Of 'Major CHDs' detected prenatally, 77% were picked up at the time of the malformation scan at weeks 18-21. CONCLUSIONS: Nearly half of 'Major CHDs' were detected...

    Until now direct neurochemical measurements during memory tasks have not been accomplished in the human basal ganglia. It has been proposed, based on both functional imaging studies and psychometric testing in normal subjects and in patients with Parkinson's disease (PD), that the basal ganglia is responsible for the performance of feedback-contingent implicit memory tasks. To measure neurotransmitters, we used in vivo microdialysis during deep brain stimulation (DBS) surgery. We show in the right subthalamic nucleus (STN) of patients with PD a task-dependent change in the concentrations of glutamate and GABA during an implicit memory task relative to baseline, while no difference was found between declarative memory tasks. The five patients studied had a significant decrease in the percent concentration of GABA and glutamate during the performance of the weather prediction task (WPT). We hypothesize, based on current models of basal ganglia function, that this decrease in the concentration is consistent with expected dysfunction in basal ganglia networks in patients with PD.

    We assessed the incidence of coronary artery disease (CAD) during hospitalization after emergency surgery for a type A acute aortic dissection. A total of 123 patients underwent multi-slice computed tomography (MSCT) scans during an early stage after surgery. The patients were divided into two groups: group I consisted of 14 patients (11.4%) who had coronary artery stenosis of more than 75% on MSCT, and group II consisted of 109 patients (88.6%) who had no coronary lesions. The prevalence of diabetes, dyslipidemia and a smoking history was significantly higher in group I. Although the serum low-density lipoprotein cholesterol levels were similar, the high-density lipoprotein cholesterol (HDL) level was significantly lower in group I (36.4 ± 7.9 mg/dl) than in group II (49.6 ± 13.5 mg/dl, P = 0.0005). The maximum carotid intima-media thickness (IMT) was significantly thicker in group I (1.17 ± 0.37 mm) compared to group II (0.96 ± 0.33 mm, P = 0.0297). The logistic regression analysis detected that a carotid IMT over 1.1 mm (odds ratio 4.35, P = 0.0371) and HDL less than 40 mg/dl (odds ratio 3.90, P = 0.0482) were predictors for CAD. CAD screening should be recommended for patients with aortic dissection who have several atherosclerosis risk factors, even after emergency surgery.

    Macrophages play an important role in non-alcoholic fatty liver disease (NAFLD). Soluble CD163 (sCD163) is a specific marker of macrophage activation. We aimed to measure sCD163 in morbidly obese patients with varying degrees of NAFLD before and after bariatric surgery (BS). Demographic, clinical, and biochemical data, and plasma sCD163 measured by enzyme-linked immunosorbent assay, of 196 patients were collected preoperatively and 3, 6, and 12 months after BS leading to significant weight loss. Peroperative liver biopsies were assessed for the NAFLD Activity Score (NAS), Kleiner fibrosis score, and the fatty liver inhibition of progression (FLIP) algorithm. In a subset, CD163 immunohistochemistry and real-time quantitative polymerase chain reaction for CD163 mRNA were performed. sCD163 was higher in patients with NAS ≥ 5 compared with those with NAS CD163-positive macrophages aligning fat-laden hepatocytes and forming microgranulomas in patients with NASH. CD163 mRNA expression did not vary with NAS. sCD163 increased in parallel with the severity of NAFLD in morbid obesity, indicating macrophage activation. BS reduced sCD163 even in patients with severe liver injury and fibrosis, suggesting full reversibility of macrophage activation associated with improved insulin sensitivity. © 2015 Journal of Gastroenterology and Hepatology Foundation and Wiley Publishing Asia Pty Ltd.

    OBJECTIVE We examined the prevalence, extent, severity, and prognosis of coronary artery disease (CAD) in individuals with and without diabetes (DM) who are similar in CAD risk factors. RESEARCH DESIGN AND METHODS We identified 23,643 consecutive individuals without known CAD undergoing coronary computed tomography angiography. A total of 3,370 DM individuals were propensity matched in a 1-to-2 fashion to 6,740 unique non-DM individuals. CAD was defined as none, nonobstructive (1–49% stenosis), or obstructive (≥50% stenosis). All-cause mortality was assessed by risk-adjusted Cox proportional hazards models. RESULTS At a 2.2-year follow-up, 108 (3.2%) and 115 (1.7%) deaths occurred among DM and non-DM individuals, respectively. Compared with non-DM individuals, DM individuals possessed higher rates of obstructive CAD (37 vs. 27%) and lower rates of having normal arteries (28 vs. 36%) (P < 0.0001). CAD extent was higher for DM versus non-DM individuals for obstructive one-vessel disease (19 vs. 14%), two-vessel disease (9 vs. 7%), and three-vessel disease (9 vs. 5%) (P < 0.0001 for comparison), with higher per-segment stenosis in the proximal and mid-segments of every coronary artery (P < 0.001 for all). Compared with non-DM individuals with no CAD, risk of mortality for DM individuals was higher for those with no CAD (hazard ratio 3.63 [95% CI 1.67–7.91]; P = 0.001), nonobstructive CAD (5.25 [2.56–10.8]; P < 0.001), one-vessel disease (6.39 [2.98–13.7]; P < 0.0001), two-vessel disease (12.33 [5.622–27.1]; P < 0.0001), and three-vessel disease (13.25 [6.15–28.6]; P < 0.0001). CONCLUSIONS Compared with matched non-DM individuals, DM individuals possess higher prevalence, extent, and severity of CAD. At comparable levels of CAD, DM individuals experience higher risk of mortality compared with non-DM individuals. PMID:22699296

    to describe the characteristics of incident cases of tuberculosis [TB] despite negative TB screening tests, in patients with inflammatory bowel disease [IBD] undergoing anti-TNF treatment, and to identify the risk factors involved. A retrospective descriptive study was conducted at GETAID centers on all IBD patients undergoing anti-TNF treatment who developed TB even though their initial screening test results were negative. The following data were collected using a standardized anonymous questionnaire: IBD, and TB characteristics and evolution, initial screening methods and results, and time before anti-TNF treatment was restarted. A total of 44 IBD patients [including 23 men; median age 37 years] were identified at 20 French and Swiss centers at which TB screening was performed [before starting anti-TNF treatment] based on Tuberculin Skin Tests [n = 25], Interferon Gamma Release Assays [n = 12], or both [n = 7]. The median interval from the start of anti-TNF treatment to TB diagnosis was 14.5 months (interquartile range [IQR] 25-75: 4.9-43.3). Pulmonary TB involvement was observed in 25 [57%] patients, and 40 [91%] had at least one extrapulmonary location. One TB patient died as the result of cardiac tamponade. Mycobacterium tuberculosis exposure was thought to be a possible cause of TB in 14 cases [32%]: 7 patients [including 6 health care workers] were exposed to occupational risks, and 7 had travelled to endemic countries. Biotherapy was restarted on 27 patients after a median period of 11.2 months [IQR 25-75: 4.4-15.2] after TB diagnosis without any recurrence of the infection. Tuberculosis can occur in IBD patients undergoing anti-TNF treatment, even if their initial screening results were negative. In the present population, TB was mostly extrapulmonary and disseminated. TB screening tests should be repeated on people exposed to occupational risks and/or travelers to endemic countries. Restarting anti-TNF treatment seems to be safe. Copyright © 2016

    The China Assessment of Antifungal Therapy in Hematological Disease study, the first large-scale observational study of invasive fungal disease (IFD) in China, enrolled 1401 patients undergoing hematopoietic stem cell transplantation (HSCT) (75.2% allogeneic and 24.8% autologous) at 31 hospitals across China. The overall incidence of proven or probable IFD was 7.7% (108 of 1401); another 266 cases (19.0%) were possible IFD. After allogeneic or autologous HSCT, the incidence of proven/probable IFD was 8.9% (94 of 1053) and 4.0% (14 of 348), respectively. Some cases (14 of 108) developed during conditioning before transplantation. The cumulative incidence of proven/probable IFD increased steeply in the first month after transplantation and after 6 months, the incidence was significantly higher in allogeneic than it was in autologous transplant recipients (9.2% versus 3.5%; P = .001) and when stem cells were derived from cord blood or bone marrow and peripheral blood (P = .02 versus other sources). Independent risk factors for proven/probable IFD in allogeneic HSCT were diabetes, HLA-matched unrelated donor, prolonged severe neutropenia (absolute neutrophil count > 500/mm(3) for >14 days), and immunosuppressants (odds ratio, 2.0 to 3.4 for all). Antifungal prophylaxis was independently protective (P = .01). Previous IFD and prolonged severe neutropenia were significant independent risk factors among autologous transplantation patients (P Transplantation. Published by Elsevier Inc. All rights reserved.

    Coronary angiography and brain computed tomography were preoperatively performed to evaluate the clinical condition of coronary artery disease and cerebrovascular disease in 101 patients (mean age, 68.4 years) with revascularization for arteriosclerosis obliterans. Eighty patients had hypertension, 12 had diabetes, and 26 had hyperlipidemia. Seventy-one patients (70.3%) had coronary stenosis. Significant stenoses in major coronary artery branches were confirmed in 35 patients, including 13 patients with old myocardial infarction. Coronary artery bypass grafting and percutaneous coronary angioplasty were performed in 2 and 7 patients with critical stenosis, respectively. Of 57 patients, who underwent brain computed tomography, abnormalities were found in 52 patients (91.2%), including cortical infarction in 9, lacunar infarction in 35, and leukoaraiosis in 27 patients. During the follow-up period 13 patients died (including 3 cases of myocardial infarction and 3 cases of stroke). Actuarial survival rate at 5 years was 80.4%. The influence of ischemic heart disease and cerebrovascular disease on early and late mortality after surgical reconstruction for peripheral occlusive vascular disease is significant. Using visual diagnostic techniques, such as coronary angiography and brain computed tomography, long term survivor should be closely observed for multiple arteriosclerotic vascular diseases.

    Background and Objectives Chronic kidney disease (CKD) is known to be a major adverse predictor in diabetes mellitus (DM) patients undergoing percutaneous coronary intervention (PCI). It is expected that the use of newer-generation drug-eluting stents (DES) would improve clinical outcomes in these patients. We evaluated the impact of CKD on clinical outcomes in diabetic patients undergoing PCI using newer-generation DES in a real-world setting. Subjects and Methods A total of 887 patients who underwent PCI with newer-generation DES and who had a history of DM or HbA1c >6.5% at the time of hospitalization were analyzed. These patients were divided into groups without CKD (n=549) and with CKD (n=338). Among survivors at discharge, a patient-oriented composite outcome (POCO) including all-cause mortality, myocardial infarction (MI), and revascularization was evaluated, together with a device-oriented composite outcome (DOCO) including cardiac death, target vessel-related MI, and target lesion revascularization at a follow-up period of one year. Results The incidence of POCO (5.4% vs. 14.0%, log-rank pCKD. According to multivariate analysis, which was adjusted for baseline differences in demographic, clinical, and angiographic factors, the presence of CKD was an independent predictor of POCO (hazard ratio [HR]: 1.82, 95% confidence interval [CI]: 1.07 to 3.12), but not of DOCO (HR 2.08, 95% CI: 0.69-6.28). Conclusion In DM patients, CKD is an independent and powerful predictor of patient-related outcomes, but not of device-related outcomes in the era of newer-generation DES. PMID:28382078

    Residual disease at the bronchial stump (RDBS) is regarded as an important factor possibly resulting in bronchopleural fistula (BPF) after lung cancer surgery, but this has not been confirmed. We conducted this meta-analysis to evaluate the effects of RDBS on BPF formation in patients undergoing lung cancer surgery. PubMed and EMBASE databases were searched for full-text articles that met our eligibility criteria. Odds ratios (ORs) with 95% confidence interval (95% CI) served as the summarized outcomes. Q-test and I(2) statistic were used to evaluate the level of heterogeneity, determining the fixed-effect model or random-effect model for quantitative synthesis. Sensitivity analysis was conducted to identify the possible origins of heterogeneity. The publication bias was assessed by Begg's test. A total of eight retrospective observational studies were included in our meta-analysis. In overall analysis, the pooled outcomes indicated that RDBS was significantly associated with BPF formation after lung cancer surgery (OR: 3.12; 95% CI: 1.72-5.64; P analysis, the pooled outcomes revealed a significantly increased risk of post-pneumonectomy BPF in patients with RDBS (OR: 2.78; 95% CI: 1.06-7.28; P = 0.037). The subgroup analysis assessing the effects of RDBS on post-lobectomy BPF was given up due to the scarcity of available data. No heterogeneity was revealed within this meta-analysis. No evidence for publication bias was detected by Begg's test. Our meta-analysis indicates that RDBS is positively associated with the increased risk of BPF in patients undergoing lung cancer surgery. The further analysis also reveals an increased risk of post-pneumonectomy BPF in patients with RDBS. More accurate and comprehensive evidence should be collected and summarized in updated meta-analyses. © The Author 2015.

Methods. 2,362 patients who underwent PCI were included in this study. Subjects were divided into 2 groups: with COPD (n=233 and without COPD (n = 2,129. Cox proportional hazards models were analyzed to determine the effect of COPD on the incidence of MACCE. Results. The patients with COPD were older (P<0.0001 and were more likely to be current smokers (P=0.02 and have had hypertension (P=0.02 and diabetes mellitus (P=0.01. Prevalence of serious cardiovascular comorbidity was higher in the patients with COPD, including a history of MI (P=0.02 and HF (P<0.0001. Compared with non-COPD group, the COPD group showed a higher risk of all-cause death (hazard ratio (HR: 2.45, P<0.0001, cardiac death (HR: 2.53, P=0.0002, MI (HR: 1.387, P=0.027, and HF (HR: 2.25, P<0.0001. Conclusions. Patients with CAD and concomitant COPD are associated with a higher incidence of MACCE (all-cause death, cardiac death, MI, and HF compared to patients without COPD. The patients with a history of COPD have higher in-hospital and long-term mortality rates than those without COPD after PCI.

    The aim of this study was to determine the patency rate after femoro-popliteal stenting followed by oral clopidogrel plus long-term aspirin. In a prospective trial, 31 patients with a total of 33 femoro-popliteal artery lesions (21 stenoses, 12 occlusions; 24 femoral, 9 popliteal) were treated with flexible tantalum stents after unsuccessful percutaneous transluminal angioplasty (PTA) preceded by local fibrinolysis in 5 of 12 patients with total occlusion. Post-interventionally, oral aspirin 100 mg was started simultaneously for the long term and was combined with an oral loading dose of 300 mg clopidogrel, followed by 75 mg clopidogrel daily for 28 days. Patients were followed for at least 12 months (maximum 34 months) by clinical examination, Doppler pressure measurement, color and duplex sonography, and angiography in case of suspicion of restenosis. In a retrospective analysis, the results were compared with those of historical groups of patients having received aspirin only (41 patients) or a long-term high-dose low molecular weight heparin (LMWH)+aspirin treatment (42 patients). Three small puncture aneurysms were treated successfully by conservative means and were categorized as minor bleeding complication. Cumulative primary patency rate (PPR) was 76{+-}7.5% (1 year), and 70{+-}9.6% (2 years) in the clopidogrel+aspirin group, thus being tendentiously better than in the aspirin-only group showing 75{+-}4.6% (1 year), and 50{+-}8.1% (2 years). Long-term high-dose LMWH+aspirin treatment showed 87{+-}5.8% (1 year), and 72{+-}9.1% (2 years), thus being superior to the other treatment regimes, with a statistically significant difference (p<0.05) between the LMWH+aspirin and the aspirin group. Clopidogrel plus aspirin is a safe medication regimen and may be effective in the prevention of early stent thrombosis. Mid- and long-term patency rate seems to be intermediate as compared with other therapeutic regimens. The LMWH+aspirin seems to be superior compared with

    The discrepancy between donor supply and organ demand increased the possibility of gender and race mismatch between the donors and recipients. However, the findings of their impact on graft and patient survival are outdated and mixed. To estimate the effects of gender and race mismatch on graft survival and patient survival among adult patients (18 years and older) with end-stage liver disease. A total of 38 768 patients undergoing liver transplant between 2002 and 2011 were identified from United Network for Organ Sharing database. Kaplan-Meier curves, log-rank tests, and Cox proportional hazard regressions with backward elimination adopting a marginal approach with a working independence assumption and stratification on recipient hepatitis C virus status were used. Posttransplantation graft survival and patient survival. Both gender mismatch (hazard ratio [HR]: 1.14, 95% confidence interval [CI]: 1.09-1.12) and race mismatch (HR 1.08, 95%C: 1.04-1.12) had significantly adverse effects on graft survival and patient survival after controlling for other factors, especially among hepatitis C-positive female recipients with male donors (HR 1.13, 95%CI 1.03-1.24), black recipients with white donors (1.39, 1.29-1.49) or Hispanic donors (HR 1.48, 95%CI 1.27-1.72), and these effects were even worse among hepatitis C-positive recipients. Gender and race mismatch between donors and recipients adversely affected graft survival and patient survival among adult patients with end-stage liver disease, both independently and after the adjustment for other factors. Future research is recommended to explore other factors such as new model for end-stage liver disease sharing policy change and disparities in access to waiting-list or transplantation.

    B-type natriuretic peptide (BNP) is a biomarker of cardiovascular disease that is common in adults with chronic kidney disease (CKD). However, in children with CKD, the range and predictive power of BNP concentrations are not known. We aimed to determine the effect of HD on BNP, as well as the prognostic impact of BNP, in end-stage renal disease (ESRD) children undergoing hemodialysis (HD). Thirty-five children with chronic renal failure (16 boys age 12.1 ± 3.7 years) on maintenance HD were included. BNP level was measured, and Doppler echocardiography was performed 30 min before (pre-HD BNP) and 30 min after (post-HD BNP) HD in each patient. An adverse event was defined as all-cause death and heart failure hospitalization. The median pre-HD BNP, the post-HD BNP, and the change in BNP were, respectively, 240 pg/ml (72 to 3346), 318 pg/ml (79 to 3788), and 9 pg/ml (-442 to 1889). Pre-HD BNP concentration was negatively correlated with left ventricular (LV) ejection fraction (r = -0.41, P = 0.018). During a mean follow-up of 39 ± 14 months, 6 patients died, and 3 were hospitalized for heart failure. Using univariate analysis, BNP before and after HD as well as Doppler tissue imaging velocities had a strong graded relationship with adverse events. Cox proportional hazards model demonstrated that pre-HD body weight (P = 0.008), pre-HD BNP (P = 0.011), and post-HD BNP (P = 0.038) remained independent predictors of adverse outcome. Even in case of ESRD, BNP still strongly correlated with LV systolic and diastolic dysfunction and was associated with mortality in HD children.

    2007-01-01

    AIM: To analyze the spectrum and risk factors of gastroesophageal reflux disease (GERD) based on presenting symptoms and endoscopic findings. METHODS: A cross-sectional survey in a cluster random sample was conducted from November 2004 to June 2005 using a validated Chinese version Reflux Disease Questionnaire (RDQ) and other items recording the demographic characteristics and potential risk factors for GERD. Subjects were defined as having GERD symptoms according to the RDQ score (>12). All subjects were endoscopied and the definition and severity of erosive esephagitis were evaluated by Los Angeles classification.The statistical analysis was performed with SPSS13.0 programs. RESULTS: Of 2231 recruited participants, 701 (31.40%) patients were diagnosed as having GFRD while 464 (20.80%) patients had objective findings of reflux esophagitis (RE). Of those 464 patients, only 291 (13.00%) were reported as subjects with GERD symptoms. A total of 528 (23.70%) patients were found to have GERD symptoms, including 19.50% patients with grade A or B reflux esophagitis, 0.90% with grade C and 0.40% with grade D. On multivariate analysis, old age,male, moderate working burden, divorced/widowed and strong tea drinking remained as significant independent risk factors for erosive esophagitis. Meanwhile, routine usage of greasy food and constipation were considered as significant independent risk factors for non-erosive reflux disease (NERD).CONCLUSION: GERD is one of the common GI diseases with a high occurrence rate in China and its main associated factors include sex, anthropometrical variables and sociopsychological characteristics.

    Purpose: Catheter-directed thrombolysis (CDT) is a highly effective approach in the treatment of deep venous thrombosis (DVT). There are no data on the primary use of CDT with argatroban and tissue plasminogen activator (tPA) in patients without heparin-induced thrombocytopenia (HIT). The aim of this study was to evaluate the efficacy and safety of the combined administration of argatroban and tPA during CDT for massive DVT in patients without HIT. Methods: Thirty-three patients with massive symptomatic iliac and femoropopliteal DVT underwent CDT with tPA and argatroban within 28 {+-} 6 h of presentation. The dose of tPA was 0.75-1 mg/h through the infusion port and that of argatroban at 0.3-1 {mu}g/kg/min through the side port of the sheath. The patients were evaluated for the efficacy and safety of CDT and recurrent symptomatic venous thromboembolism (VTE) at a mean follow-up of 22 months. Results: There was no bleeding or iatrogenic pulmonary embolism with the CDT regimen we used. Grade III lysis (complete resolution of thrombus on venography) was achieved in 30 patients (91 %). In 3 patients with additional inferior vena cava filter thrombosis, further thrombectomy of the filter was required. No patient developed recurrent VTE. Conclusion: Concomitant administration of argatroban and tPA is a highly safe and effective regimen for CDT for massive DVT.

    Currently, the tumor-node-metastasis (TNM) system is used in hepatectomy patients for tumor staging of HCC patients. However this can only evaluate the histopathological factor. MELD score is an objective measure for liver function widely used as a severity index for priority on the waiting list for liver transplantation. Here we suggest a modified TNM staging system based on the MELD score and test its relation with post-operative outcome of HCC. We retrospectively collected 922 HCC patients undergoing hepatic resection, with TNM stage I (n=239), stage II (n=375) and stage III (n=308); giving points 0 to 2 for each stage (from I to III). Pre-operative MELD score was calculated and assigned 0 points for MELD 8. The two scores were added together to form a modified MELD-base TNM stage score and tested the correlation of this new scoring system with outcome after liver resection. The modified MELD-base TNM stage score resulted in score 0 (n=114), score 1 (n=247), score 2 (n=335), score 3 (n=164), and score 4 (n=62). The disease-free survival in each group showed significant difference (pTNM staging system reliably separates patients with HCC into homogeneous groups with respect to post-resectional prognosis. Further prospective validation studies are required to confirm the feasibility of this strategy.

    Radiomic features derived from the texture analysis of different imaging modalities e show promise in lesion characterisation, response prediction, and prognostication in lung cancer patients. The present study aimed to identify an images-based radiomic signature capable of predicting disease-free survival (DFS) in non-small cell lung cancer (NSCLC) patients undergoing surgery. A cohort of 295 patients was selected. Clinical parameters (age, sex, histological type, tumour grade, and stage) were recorded for all patients. The endpoint of this study was DFS. Both computed tomography (CT) and fluorodeoxyglucose positron emission tomography (PET) images generated from the PET/CT scanner were analysed. Textural features were calculated using the LifeX package. Statistical analysis was performed using the R platform. The datasets were separated into two cohorts by random selection to perform training and validation of the statistical models. Predictors were fed into a multivariate Cox proportional hazard regression model and the receiver operating characteristic (ROC) curve as well as the corresponding area under the curve (AUC) were computed for each model built. The Cox models that included radiomic features for the CT, the PET, and the PET+CT images resulted in an AUC of 0.75 (95%CI: 0.65-0.85), 0.68 (95%CI: 0.57-0.80), and 0.68 (95%CI: 0.58-0.74), respectively. The addition of clinical predictors to the Cox models resulted in an AUC of 0.61 (95%CI: 0.51-0.69), 0.64 (95%CI: 0.53-0.75), and 0.65 (95%CI: 0.50-0.72) for the CT, the PET, and the PET+CT images, respectively. A radiomic signature, for either CT, PET, or PET/CT images, has been identified and validated for the prediction of disease-free survival in patients with non-small cell lung cancer treated by surgery.

    Patients undergoing cardiac surgery presenting with chronic obstructive pulmonary disease (COPD) have a higher 30-day mortality risk. In these patients, pulmonary dysfunction linked to an inflammatory response is frequent after cardiac operations using cardiopulmonary bypass (CPB), which causes pulmonary hypoperfusion. We hypothesize that selective pulmonary perfusion (sPP) of the lungs leads to a reduction of pulmonary inflammation and a better clinical outcome. Fifty-nine COPD patients (forced expiratory volume in 1 s/vital capacity undergoing cardiac surgery procedures (coronary artery bypass grafting 64%, valve 14%) were block-randomized to sPP (venous blood, temperature 2°C, 4 l) or standard CPB (28/28). The primary end-point of the study was to evaluate the effect of pulmonary perfusion on gas exchange by measuring alveolar-arterial oxygen gradient. The surrogate end-points were inflammatory response, intensive care unit (ICU) stay, time on respirator (TOR) and major adverse cardiac and cerebrovascular events. A cytokine assay for interleukin-1β, IL-6, IL-10, tumour necrosis factor-α (TNF-α) and polymorphonuclear elastase was performed with peripheral blood at different time-points [(t1) pre-CPB, (t2) end of CPB, (t3) 3 h, (t4) 24 h, (t5) 48 h postoperatively]. Repeated-measure analysis of variance and non-parametric statistics were used to assess the between-group and during time differences. The two groups proved comparable for perioperative variables. Serum cytokines were not different in the two groups throughout the study (P > 0.05 at single time-points), but as a function of time, the markers of the inflammatory response increased after CBP (P blood during CPB may have a protective effect on the lungs. A multicentre study design and larger cohort seem necessary to demonstrate the benefits of sPP more clearly. © The Author 2014.

    Children diagnosed with congenital heart disease often undergo cardiac catheterization for their treatment, which involves the use of ionizing radiation and therefore a risk of radiation-induced cancer. The purpose of this study was to calculate the effective and equivalent organ doses (H{sub T}) in those children and estimate the risk of exposure-induced death. Fifty-three children were divided into three groups: atrial septal defect (ASD), ventricular septal defect (VSD) and patent ductus arteriosus (PDA). In all procedures, the exposure conditions and the dose-area product meters readings were recorded for each individual acquisition. Monte Carlo simulations were run using the PCXMC 2.0 code and mathematical phantoms simulating a child's anatomy. The H{sub T} values to all irradiated organs and the resulting E and risk of exposure-induced death values were calculated. The average dose-area product values were, respectively, 40 {+-} 12 Gy.cm{sup 2} for the ASD, 17.5 {+-} 0.7 Gy.cm{sup 2} for the VSD and 9.5 {+-} 1 Gy.cm{sup 2} for the PDA group. The average E values were 40 {+-} 12, 22 {+-} 2.5 and 17 {+-} 3.6 mSv for ASD, VSD and PDA groups, respectively. The respective estimated risk of exposure-induced death values per procedure were 0.109, 0.106 and 0.067%. Cardiac catheterizations in children involve a considerable risk for radiation-induced cancer that has to be further reduced. (orig.)

    In asymptomatic end-stage renal disease (ESRD) patients undergoing vasodilator stress myocardial perfusion imaging (MPI) prior to renal transplantation (RT), the impact of pre-transplant heart rate response (HRR) to vasodilator stress on post-RT outcomes is unknown. We analyzed a retrospective cohort of asymptomatic patients with ESRD who underwent a vasodilator stress SPECT-MPI and subsequently received RT. Blunted HRR was defined as HRR <28% for regadenoson stress and <20% for adenosine stress. The primary endpoint was major adverse cardiac events (MACE), defined as cardiac death or myocardial infarction. Clinical risk was assessed using the sum of risk factors set forth by the AHA/ACCF consensus statement on the assessment of RT candidates. Among 352 subjects, 140 had an abnormal pre-transplant HRR. During a mean follow-up of 3.2 ± 2.0 years, 85 (24%) MACEs were observed. Blunted HRR was associated with increased MACE risk (hazard ratio 1.72; 95% confidence interval 1.12-2.63, P = 0.013), and remained significant after adjustment for gender, sum of AHA/ACCF risk factors, summed stress score, baseline heart rate, and β-blocker use. HRR was predictive of MACE in patients with normal MPI and irrespective of clinical risk. Blunted HRR was associated with a significant increase in post-operative (30-day) MACE risk (17.9% vs 8.5%; P = 0.009). In asymptomatic ESRD patients being evaluated for RT, a blunted pre-transplant HRR was predictive of post-RT MACE. HRR may be a valuable tool in the risk assessment of RT candidates.

    To evaluate the association of ABO blood type with clinicopathologic outcomes and mortality among patients with urothelial carcinoma of the bladder treated with radical cystectomy (RC). We identified 2,086 consecutive patients who underwent RC between 1980 and 2008. Postoperative recurrence-free survival (RFS) and cancer-specific survival (CSS) were estimated using the Kaplan Meier method and compared with the log-rank test. Cox proportional hazards regression models were used to evaluate the association of ABO blood type with outcomes. A total of 913 (44%), 881 (42%), 216 (10%), and 76 (4%) patients had blood type O, A, B, and AB, respectively. Median postoperative follow-up among survivors was 11.0 years (interquartile range: 7.7-15.9y). Overall, 1,561 patients died, with 770 deaths attributable to bladder cancer. Non-O blood type was associated with significantly worse 5-year RFS (65% vs. 69%; P = 0.04) and/or CSS (64% vs. 70%; P = 0.02). In particular, among patients with≤pT2N0 disease, the 5-year RFS for those with non-O vs. O blood type was 75% vs. 82%, respectively (P = 0.002), whereas the 5-year CSS was 77% vs. 85%, respectively (P = 0.001). Moreover, on multivariable analysis, blood type A remained independently associated with an increased risk of cancer-specific mortality (hazard ratio = 1.22; P = 0.01). Non-O blood type, particularly blood type A, is associated with a significantly increased risk of death from bladder cancer among patients undergoing RC. If validated, the utility of a multimodal therapy approach, including perioperative chemotherapy, or more frequent postoperative surveillance in this cohort warrants further study.

    Objective Little is known about long-term outcomes among patients who receive percutaneous angioplasty (PTA) for peripheral artery disease (PAD) then undergo below-knee or above-knee amputations. We sought to determine clinical outcomes associated with below-knee or above-knee amputation, along with possible explanatory factors and treatment strategies. Methods Using data from Taiwan’s National Health Insurance Research Database from 1997 to 2010, 7,568 adult patients were divided into three groups: lower extremity preserved (LE), below-knee amputation (BK) and above-knee amputation (AK). We assessed outcomes including major adverse cardiovascular events (MACE) and associated risk factors. Results Overall MACE was significantly higher in the AK group compared to the LE and BK groups, over a mean follow-up of 2.45 years (hazard ratio [HR]: 1.81; 95% confidence interval [CI]: 1.50–2.18 for AK vs. LE; HR: 1.67; 95% CI: 1.36–2.06 for AK vs. BK). However MACE were similar for the BK and LE groups (HR: 1.08; 95% CI: 0.98–1.20). Overall mortality was highest in the AK group (HR: 1.65, 95% CI: 1.34–2.04 for AK vs. BK). As for patient characteristics, atrial fibrillation was more prevalent in the AK group than in the BK group (17% vs. 7%). Independent risk factors associated with death after above- or below-knee amputation included advanced age, heart failure, dialysis, male gender and high patient volume. Conclusion The MACE rate was highest in the AK group, whereas the LE and BK groups were similar in this regard. Furthermore, overall mortality increased with larger area of amputation. PMID:25354252

    Peritoneal dialysis is one of the main modality of treatment in end-stage kidney diseases (ESKD) in children. In our previous work in chronic kidney disease patients, in pre-dialyzed period and on hemodialysis, the neutrophils were highly activated. The aim of this study was to assess an inflammatory condition and neutrophil activation in ESKD patients undergoing continuous ambulatory peritoneal dialysis (CAPD). Thirteen CAPD patients without infection, both sexes, aged 2.5-24 years, and group of healthy subjects (C) were studied. For comparative purposes the conservatively treated (CT) group of ESKD patients was included. Neutrophil elastase in complex with α1-proteinase inhibitor (NE-α1PI; ELISA), α1-proteinase inhibitor (α1PI; radial immunodiffusion) and interleukin-8 (IL-8; ELISA) were measured in the blood samples from CAPD, CT, and C group and in the peritoneal dialysate fluid (PDF) samples of patients on CAPD. A significantly increased plasma NE-α1PI levels (median 176.5 μg/L, range 85.2-373.2 μg/L; p < 0.00005), serum IL-8 (median 18.6 pg/mL, range 15.73-35.28 pg/mL; p < 0.05), and slightly decreased serum α1PI (median 1,540 mg/L, range 1,270-1,955; p ≤ 0.05) compared to the control groups were found. There were no significant differences of analyzed parameters between CAPD and CT patients. The concentration ratio of NE-α1PI, α1PI and IL-8 in blood/PDF was 29.97, 8.24, and 4.48, respectively. There were significantly positive correlations between serum and PDF concentration of α1PI and IL-8 (r = 0.613, p < 0.05; r = 0.59; p < 0.005, respectively). The results of our study demonstrate that neutrophils are highly activated in non-infected CAPD patients. The pivotal marker of this activation is NE-α1PI. It may contribute to chronic inflammation and tissues injury.

    Background There have been many studies investigating the impact of the model for end-stage liver disease (MELD) score on predicting post-transplant outcome. But it is unclear whether MELD is correlated to intraoperative fluid therapy and coagulation status. We investigated the relationship between the severity of liver diseases as measured by MELD score and intraoperative fluid requirements and the changes of coagulation characteristics. Methods Ninety patients were included in this retrospective study. The patients were stratified into three groups according to the MELD scores: <15 (low), 15-25 (medium) and >25 (high). Intraoperatively, volume was restored with allogeneic and/or salvaged red blood cells (RBC), fresh-frozen plasma (FFP), platelet and other types of fluids according to hemodynamic data, hematocrit, and clotting data. Intraoperative coagulation data, blood requirements and other fluids administered were compared among the 3 groups. Results Before surgery, in addition to the three variables used to calculate MELD scores in other baseline laboratory values, including ratio of activated partial thromboplastin time (R-APTT), D-Dimer, hematocrit, platelet and blood urea nitrogen (BUN) were significantly different among the 3 groups. The blood loss increased with increasing MELD. The volume of RBC (allogeneinc, salvaged and total), FFP, platelet and the total volume of transfusion were also significantly different among the three groups (P<0.01). The requirements for prothrombin complex and fibrinogen showed a similar pattern. During operation, the changing trends of each coagulation variable were different. Compared with baseline, during each intraoperative stage, INR and R-APPT increased in the low MELD group. While in the medium MELD and high MELD groups, INR did not changed significantly during the operation, and R-APPT significantly increased only after reperfusion. Conclusions This study provided some useful information for perioperative

    Inhalational anesthesia with sevoflurane for endotracheal intubation without muscle relaxant is now used widely for pediatric patients. This study assessed the efficacy and safety of induction with high concentration sevoflurane and of nasotracheal intubation without muscle relaxant in infants with increased or decreased pulmonary blood flow (PBF) and undergoing surgery for congenital heart diseases. Fifty-five infants aged 2 - 12 months, weighing 4.7 - 10.0 kg, and scheduled for congenital cardiac surgery were enrolled. Subjects were divided into those with increased (IPBF group, n = 29) and decreased (DPBF group, n = 26) pulmonary blood flow. All infants received inhalational induction with 8% sevoflurane in 100.0% oxygen at a gas flow rate of 6 L/min. Nasotracheal intubation was performed 4 minutes after induction. Sevoflurane vaporization was decreased to 4.0% for placement of a peripheral intravenous line and invasive hemodynamic monitors. Five minutes later, sedatives and muscle relaxant were administered and the vaporizer was adjusted to 2% for maintenance of anesthesia. Bispectral index (BIS) scores, circulatory parameters, satisfactory and successful intubation ratios, adverse reactions, and complications of intubation were recorded. Times to loss of lash and pain reflexes were longer for the DPBF group (P intubation ratios were 93.1% and 61.5% for the IPBF and DPBF groups, respectively (P = 0.008). Successful intubation ratios were 96.6% and 76.9% for the IPBF and DPBF groups, respectively (P = 0.044). Following sevoflurane inhalation, blood pressures decreased significantly in the IPBF group but remained stable in the DPBF group. BIS scores declined to similar stable values, and a "nadir BIS" was recorded for both groups. No obvious adverse reactions or complications of intubation were noted perioperatively. Induction with high concentration sevoflurane, although faster for infants with IPBF, is safe for infants with IPBF or DPBF. However, nasotracheal

    To associate MRI textural analysis (MRTA) with MRI and histological Crohn's disease (CD) activity. Sixteen patients (mean age 39.5 years, 9 male) undergoing MR enterography before ileal resection were retrospectively analysed. Thirty-six small (≤3 mm) ROIs were placed on T2-weighted images and location-matched histological acute inflammatory scores (AIS) measured. MRI activity (mural thickness, T2 signal, T1 enhancement) (CDA) was scored in large ROIs. MRTA features (mean, standard deviation, mean of positive pixels (MPP), entropy, kurtosis, skewness) were extracted using a filtration histogram technique. Spatial scale filtration (SSF) ranged from 2 to 5 mm. Regression (linear/logistic) tested associations between MRTA and AIS (small ROIs), and CDA/constituent parameters (large ROIs). Skewness (SSF = 2 mm) was associated with AIS [regression coefficient (rc) 4.27, p = 0.02]. Of 120 large ROI analyses (for each MRI, MRTA feature and SSF), 15 were significant. Entropy (SSF = 2, 3 mm) and kurtosis (SSF = 3 mm) were associated with CDA (rc 0.9, 1.0, -0.45, p = 0.006-0.01). Entropy and mean (SSF = 2-4 mm) were associated with T2 signal [odds ratio (OR) 2.32-3.16, p = 0.02-0.004], [OR 1.22-1.28, p = 0.03-0.04]. MPP (SSF = 2 mm) was associated with mural thickness (OR 0.91, p = 0.04). Kurtosis (SSF = 3 mm), standard deviation (SSF = 5 mm) were associated with decreased T1 enhancement (OR 0.59, 0.42, p = 0.004, 0.007). MRTA features may be associated with CD activity. (orig.)

    Sleep disorders for patients on dialysis are significant causes of a poorer quality of life and increased morbidity and mortality. No study has evaluated patients undergoing automated peritoneal dialysis (APD) to assess their sleep disorders compared to hemodialysis (HD) and continuous ambulatory peritoneal dialysis (CAPD). A total of 166 clinically stable patients who had been on dialysis for at least 3 months were randomly selected for the study and divided into HD, CAPD or APD. Socio-demographic, clinical and laboratory parameters and self-administered questionnaires were collected for the investigation of insomnia, restless legs syndrome (RLS), bruxism, rapid eye movement sleep behavior disorder, excessive daytime sleepiness (EDS), obstructive sleep apnea syndrome (OSAS), sleepwalking, sleep hygiene, depression and anxiety. Insomnia was detected in more than 80 % of patients on the three modalities. OSAS was lower for patients on HD (36 %) than on CAPD (65 %) (p dialysis modalities studied had a high prevalence of sleep disorders. Patients on HD had a lower proportion of OSAS than those on CAPD and APD, which is most likely attributed to their lower body mass indices. The possible causes of higher RLS rates in APD patients have not been established.

    During cardiac failure, cardiomyocytes have difficulty in using the substrates to produce energy. L-carnitine is a necessary nutrient for the transport of fatty acids that are required for generating energy. Coronary artery graft surgery reduces the plasma levels of L-carnitine and increases the oxidative stress. This study demonstrates the effect of L-carnitine supplementation on the reverse remodeling of patients undergoing coronary artery bypass graft. Patients with ischemic heart failure who underwent coronary graft surgery were randomized to group A - supplemented with L-carnitine or group B controls. Left ventricular ejection fraction, left ventricular systolic and diastolic diameters were assessed preoperatively, 60 and 180 days after surgery. Our study included 28 patients (26 [93.0%] males) with a mean age ± SD of 58.1 ± 10.5 years. The parameters for the evaluation of reverse remodeling did not improve after 60 and 180 days of coronary artery bypass grafting in comparison between groups (p > 0.05). Evaluation within the L-carnitine group showed a 37.1% increase in left ventricle ejection fraction (p = 0.002) and 14.3% (p = 0.006) and 3.3% (p > 0.05) reduction in systolic and diastolic diameters, respectively. L-carnitine supplementation at a dose of 50 mg/kg combined with artery bypass surgery did not demonstrate any additional benefit in reverse remodeling. However, evaluation within the L-carnitine group may indicate a clinical benefit of L-carnitine supplementation.

    Patients with psoriasis, in particular those with severe disease, have an increased risk of cardiovascular (CV) events compared with the general population. The aim of the present study is to determine whether correlation between asymmetric dimethylarginine (ADMA) and osteoprotegerin (OPG), two biomarkers associated with CV disease, and disease severity may exist in patients with moderate-to-severe psoriasis. We also aimed to establish if baseline serum levels of these two biomarkers could correlate with the degree of change in the clinical parameters of disease severity following the use of anti-tumor necrosis factor (TNF)-α therapy in these patients. This was a prospective study on a series of consecutive non-diabetic patients with moderate-to-severe psoriasis who completed 6 months of therapy with anti-TNF-α-adalimumab. Patients with kidney disease, hypertension or body mass index of 35 kg/m(2) or more were excluded. Metabolic and clinical evaluation was performed immediately prior to the onset of treatment and at month 6. Twenty-nine patients were assessed. Unlike OPG, a significant positive correlation between ADMA and resistin serum levels was found at the onset of adalimumab and also after 6 months of biologic therapy. We also observed a positive correlation between the percent of body surface area affected (BSA) and ADMA levels obtained before the onset of adalimumab and a negative correlation between baseline ADMA levels and a 6-month BSA change compared with baseline results. In patients with moderate-to-severe psoriasis, ADMA levels correlate with clinical markers of disease severity.

    Full Text Available Maintenance of sinus rhythm (SR is superior to rate control in atrial fibrillation (AF. In order to achieve SR, we administered single-dose intravenous amiodarone intraoperatively and evaluated its effect on conversion of rheumatic AF to SR in patients undergoing valvular heart surgery. Patients were randomly assigned to amiodarone ( n = 42 or control ( n = 40 group in a double blind manner. The amiodarone group received amiodarone (3 mg/kg intravenously prior to the institution of cardiopulmonary bypass and the control group received the same volume of normal saline. In the amiodarone group, the initial rhythm after the release of aortic cross clamp was noted to be AF in 14.3% ( n = 6 and remained so in 9.5% ( n = 4 of patients till the end of surgery. In the control group, the rhythm soon after the release of aortic cross clamp was AF in 37.5% ( n = 15 ( p = 0.035 and remained so in 32.5% ( n = 13 of patients till the end of surgery ( p = 0.01. At the end of first post-operative day 21.4% ( n = 9 of patients in amiodarone group and 55% ( n = 22 of patients in control group were in AF ( p = 0.002. The requirement of cardioversion/defibrillation was 1.5 (±0.54 in amiodarone group and 2.26 (±0.73 in the control group ( p = 0.014, and the energy needed was 22.5 (±8.86 joules in the amiodarone group and 40.53 (±16.5 in the control group ( p = 0.008. A single intraoperative dose of intravenous amiodarone increased the conversion rate of AF to normal sinus rhythm, reduced the need and energy required for cardioversion/defibrillation and reduced the recurrence of AF within one day.

    Patients with Alzheimer's disease after an initial response to cholinesterase inhibitors may complain a later lack of efficacy. This, in association with incident neuropsychiatric symptoms, may worsen patient quality of life. Thus, the switch to another cholinesterase inhibitor could represent a valid therapeutic strategy. The aim of this study was to investigate the effectiveness of the switch from one to another cholinesterase inhibitor on cognitive and affective symptoms in mild to moderate Alzheimer disease patients. Four hundred twenty-three subjects were included from the EVOLUTION study, an observational, longitudinal, multicentre study conducted on Alzheimer disease patients who switched to different cholinesterase inhibitor due either to lack/loss of efficacy or response, reduced tolerability or poor compliance. All patients underwent cognitive and neuropsychiatric assessments, carried out before the switch (baseline), and at 3 and 6-month follow-up. A significant effect of the different switch types was found on Mini-Mental State Examination score during time, with best effectiveness on mild Alzheimer's disease patients switching from oral cholinesterase inhibitors to rivastigmine patch. Depressive symptoms, when measured using continuous Neuropsychiatric Inventory values, decreased significantly, while apathy symptoms remained stable over the 6 months after the switch. However, frequency of both depression and apathy, when measured categorically using Neuropsychiatric Inventory cut-off scores, did not change significantly during time. In mild to moderate Alzheimer disease patients with loss of efficacy and tolerability during cholinesterase inhibitor treatment, the switch to another cholinesterase inhibitor may represent an important option for slowing cognitive deterioration. The evidence of apathy stabilization and the positive tendency of depressive symptom improvement should definitively be confirmed in double-blind controlled studies.

Among patients, 229 (75.8% were female and 155 (51.3% were Caucasian; the mean age was 50.3 ± 12.8 years, and the mean disease duration was 9.9 ± 8.7 years. Among them 214 patients (70.9% received adalimumab, 72 (23.8% etanercept, and 16 (5.3% infliximab. Mean Health Assessment Questionnaire-Disability Index (HAQ-DI was 1.37 ± 0.67 for all participants. Poor functional response was associated with female gender, married patients and with a score of < 0.6 on the EuroQoL-5 dimensions (EQ-5D. Significant correlation was found between the HAQ-DI values, disease activity and quality of life (QOL. The results obtained in this study contribute to a better understanding of the clinical and demographic characteristics of patients with rheumatic diseases at the beginning of anti-TNF-agent treatment by SUS. Furthermore, our findings are consistent with another Brazilian and foreign cross-sectional investigations. This knowledge can be of great importance for further studies evaluating the effectiveness of biological agents, as well as, to contribute to improve the well-being of the patients with rheumatic diseases.

    . Endovascular approaches are favored for most candidates with aortoiliac disease and for selected patients with femoropopliteal disease in whom anatomic durability is expected to meet this minimum threshold. Conversely, caution is warranted in the use of interventions for IC in anatomic settings where durability is limited (extensive calcification, small-caliber arteries, diffuse infrainguinal disease, poor runoff). Surgical bypass may be a preferred strategy in good-risk patients with these disease patterns or in those with prior endovascular failures. Common femoral artery disease should be treated surgically, and saphenous vein is the preferred conduit for infrainguinal bypass grafting. Patients who undergo invasive treatments for IC should be monitored regularly in a surveillance program to record subjective improvements, assess risk factors, optimize compliance with cardioprotective medications, and monitor hemodynamic and patency status.

    Several randomized controlled trials (RCTs) have shown the superiority of some of these technologies over balloon angioplasty, but direct comparisons between these treatment options are lacking. The authors conducted a network meta-analysis of RCTs comparing bare nitinol stents, covered nitinol stents, paclitaxel- or sirolimus-eluting stents (PES or SES), and paclitaxel-coated balloons (PCB) with plain balloon angioplasty or with each other in the femoropopliteal artery (PROSPERO registry: CRD42013004845). Sixteen RCTs comprising 2532 patients with 4227 person-years of follow-up were analyzed on an intention-to-treat basis. Bayesian random effects Poisson and binomial models were used for mixed treatment comparisons (WinBUGS). Clinical heterogeneity was accounted for by incorporating a meta-regression model on trial-specific baseline risk. End points included technical success, vascular restenosis, target lesion revascularization, and major amputations. Pairwise odds ratios and rate ratios (ORs and RRs) of absolute treatment effects were calculated, and the probabilities of each treatment being best are reported. Summary estimates are reported as the posterior median and associated credible intervals (CrIs) that serve the same purpose as confidence intervals in the context of the Bayesian framework. Extensive sensitivity, meta-regression, and network consistency analyses were performed to evaluate heterogeneity. Technical success was highest with covered stents (pooled OR, 13.6; 95% CrI, 3.3-31.1, probability best 82%) followed by uncovered stents (pooled OR, 7.0; 95% CrI, 2.6-129, probability best 18%) when compared with balloon angioplasty (reference treatment). Vascular restenosis was lowest with PES (RR, 0.43; 95% CrI, 0.16-1.18, probability best 45%) followed by PCB (RR, 0.43; 95% CrI, 0.26-0.67, probability best 42%). Target lesion revascularization was lowest with PCB (RR, 0.36; 95% CrI, 0.23-0.55, probability best 56%) followed by PES (RR, 0.42; 95% CrI, 0

    This study aimed at analysing long-term oncologic outcomes in prostate cancer patients with limited nodal disease (1-2 positive lymph nodes) without adjuvant therapy after radical prostatectomy (RP). We retrospectively analysed data of 209 pN1 patients who underwent RP between January 1998 and 2010 with one (160) or two (49) histologically proven positive lymph nodes (LNs) without adjuvant treatment. Biochemical recurrence-free survival, metastasis-free survival and cancer-specific survival (CSS) were reported. In multivariable regression analyses further prognosticators of oncologic outcome in these patients were analysed. Median follow-up was 60.2 months. There was no significant difference in oncologic outcome between patients with one and two positive LNs. 73.1% (76.7%) of patients with one (two) positive LNs had biochemical recurrence during the follow-up period, 20.0% (25.6%) developed metastasis and 8.1% (6.1%) died of their disease. The only factors significantly associated with oncologic outcome in multivariable analysis were Gleason score and pT-stage. Patients with limited nodal disease (1-2 positive LNs) without adjuvant therapy showed favourable CSS-rates above 94% after 5 years. A subgroup of these patients (37%) remained metastasis-free without need of salvage treatment.

    A 256-slice coronary computed tomography angiography (CCTA) is an accurate method for detection and exclusion of obstructive coronary artery disease (OBS-CAD). However, accurate image interpretation requires expertise and may not be available at all hours. The purpose of this study was to evaluate the usefulness of a fully automated computer-assisted diagnosis (COMP-DIAG) tool for exclusion of OBS-CAD in patients in the emergency department (ED) presenting with chest pain. Three hundred sixty-nine patients in ED without known coronary disease underwent 256-slice CCTA as part of the assessment of chest pain of uncertain origin. COMP-DIAG (CorAnalyzer II) automatically reported presence or exclusion of OBS-CAD (>50% stenosis, ≥1 vessel). Performance characteristics of COMP-DIAG for exclusion and detection of OBS-CAD were determined using expert reading as the reference standard. Seventeen (5%) studies were unassessable by COMP-DIAG software, and 352 patients (1,056 vessels) were therefore available for analysis. COMP-DIAG identified 33% of assessable studies as having OBS-CAD, but the prevalence of OBS-CAD on CCTA was only 18% (66 of 352 patients) by standard expert reading. However, COMP-DIAG correctly identified 61 of the 66 patients (93%) with OBS-CAD with 21 vessels (2%) with OBS-CAD misclassified as negative. In conclusion, compared to expert reading, automated computer-assisted diagnosis using the CorAnalyzer showed high sensitivity but only moderate specificity for detection of obstructive coronary disease in patients in ED who underwent 256-slice CCTA. The high negative predictive value of this computer-assisted algorithm may be useful in the ED setting.

    The radioiodine is used as complementary treatment of thyroid cancer and as first choice for the treatment of Graves' disease, being efficient, safe and easy administration, but without there is a protocol defined. This work was evaluated the thyroid absorbed dose from its mass and maximum uptake of I-131 obtained in the examination of diagnostic radiology of radiotherapeutic patients undergoing treatment of Graves' disease. Based on the results, it is observed that the thyroid absorbed dose, as much in terms of mass as the maximum uptake of I-131 for different values of administered activity, varies significantly. The analysis of these parameters is an excellent indicator for the pre-define quantity of radionuclide that is administered to the patient in terms of the radiation dose required to achieve an efficient therapeutic treatment. Moreover, it was observed that the thyroid absorbed dose depends on the degree of pathology of the disease, its mass and of the maximum uptake of I-131. (author)

    To examine the safety and efficacy of cangrelor in patients with single-vessel disease (SVD) and multi-vessel disease (MVD). Cangrelor, an intravenous, rapidly acting P2Y12 inhibitor, is superior to clopidogrel in reducing ischemic events among patients receiving percutaneous coronary intervention (PCI). We studied a modified intention to treat population of patients with SVD and MVD from the CHAMPION PHOENIX trial. The primary efficacy outcome was the composite of death, myocardial infarction (MI), ischemia-driven revascularization (IDR), and stent thrombosis (ST) at 48hours. The key safety outcome was non-coronary artery bypass grafting GUSTO severe bleeding at 48hours. Among 10,921 patients, 5,220 (48%) had SVD and 5,701 (52%) had MVD. MVD patients were older and more often had diabetes, hyperlipidemia, hypertension, prior stroke, and prior MI. After adjustment, MVD patients had similar rates of 48-hour death/MI/IDR/ST (6.3% vs 4.2%, adjusted odds ratio [OR] 1.6 [95% CI 0.42-6.06]) and GUSTO severe bleeding (0.1% vs 0.2%, P=.67) compared with SVD patients. Consistent with overall trial findings, cangrelor use reduced ischemic complications in patients with both SVD (3.9% vs 4.5%; OR 0.86, 95% CI 0.65-1.12) and MVD (5.5% vs 7.2%; OR 0.74, 95% CI 0.6-0.92, P-interaction=.43). GUSTO severe bleeding outcomes were not significantly increased with cangrelor or clopidogrel in either SVD or MVD patients. In the CHAMPION PHOENIX trial, MVD and SVD patients had similar ischemic outcomes at 48hours and 30days. Cangrelor consistently reduced ischemic complications in both SVD and MVD patients without a significant increase in GUSTO severe bleeding. CLINICAL PERSPECTIVES. Copyright © 2017 Elsevier Inc.

    Presented herein are the outcomes of a total of 80 operations of femoropopliteal grafting above the knee-joint fissure, carried out using a vascular prosthesis made of polytetrafluoroethylene (PTFE) in patients diagnosed with atherosclerotic lesions of the arteries of the lower extremities over the period between February 1995 and December 2005 at the Department of Vascular Surgery of the A. V. Vishnevsky Institute of Surgery of the Russian Academy of Medical Sciences. Fifty percent of the patients were operated on for grade II B ischemia, while 13.7% of the patients suffered from grade III ischaemia of the lower limb, and 29 (36.3%) subjects were found to have grade IV ischaemia. The condition of the distal bed was considered in 41.2% of the patients, being defined as in 48.5%, and as "poor" in 10.3%. The operative intervention was carried out according to the conventionally accepted technique. 50% of the reconstructions were performed using the prosthesis 8 mm in diameter, and 50% - using that measuring 6 mm in diameter. A statistically significant impact of the diameter of the prosthesis used on the patency of the graft in the remote postoperative period was revealed: with the prosthesis 8-mm in diameter, the patency after 12, 30 and 60 months amounted to 93%, 64% and 51%, respectively, while with the transplant measuring 6 mm in diameter, these indices at the above-mentioned time intervals did not exceed 62%, 44% and 31%, respectively (P=0.004).

    Full Text Available Background and Objectives: Patients with chronic kidney disease (CKD are more prone for bleeding following percutaneous renal intervention, as compared to those with normal renal function. Causes are multi-factorial. Finding multiple aneurysms away from the site of renal intervention following initial angioembolization for hemorrhage is very unusual in these patients. Materials and Methods: Clinical and radiological findings of all the patients who underwent renal angiography for post-intervention bleed for a period of 5 years were reviewed and analyzed. Results: A total of 29 patients required angiography for post-intervention hemorrhage. Six patients had recurrence of hemorrhage for which they underwent repeat angiography. Four of these patients had appearance of multiple new aneurysms away from the site of percutaneous nephrostomy (PCN/percutaneous nephrolithotomy (PNL puncture and the site of previous bleeding. All the patients had CKD (creatinine >2.5 mg/dl. They were on prolonged preoperative urinary diversion and had polymicrobial urinary infection. Three patients had candiduria. None of these patients had re-bleeding after repeat embolization and treatment with antibacterial and antifungal agents. Conclusions: Development of multiple aneurysms away from the sites of punctures in patients with CKD following percutaneous intervention is very unusual. Its causation including infection with bacteria and fungus, reaction of embolizing material, and angiopathy needs to be explored.

    Peak VO2, as measure of physical performance is central to a correct preoperative evaluation in patients with both non-small-cell lung cancer (NSCLC) and chronic obstructive pulmonary disease (COPD) because it is closely related both to operability criteria and the rate of postoperative complications. Strategies to improve peak VO2, as a preoperative pulmonary rehabilitation programme (PRP), should be considered favourably in these patients. In order to clarify the role of pulmonary rehabilitation, we have evaluated the effects of 3-week preoperative high-intensity training on physical performance and respiratory function in a group of patients with both NSCLC and COPD who underwent lobectomy. We studied 40 patients with both NSCLC and COPD, age PRP, while Group S underwent only lobectomy. We evaluated peak VO2 in all patients at Time 0 (T0), after PRP/before surgery in Group R/S (T1) and 60 days after surgery, respectively, in both groups (T2). There was no difference between groups in peak VO2 at T0, while a significant difference was observed both at T1 and T2. In Group R, peak VO2 improves significantly from T0 to T1: 14.9 ± 2.3-17.8 ± 2.1 ml/kg/min ± standard deviation (SD), P PRP was a valid preoperative strategy to improve physical performance in patients with both NSCLC and COPD and this advantage was also maintained after surgery.

    Current evidence suggests that angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) reduce the incidence of new atrial fibrillation (AF) in a variety of clinical conditions, including the treatment of left ventricular dysfunction or hypertension. Here we assessed whether ACEIs and ARBs could decrease incidence of new-onset AF in patients with end-stage renal disease (ESRD). We identified patients from the Registry for Catastrophic Illness, a nation-wide database encompassing almost all of the patients receiving dialysis therapy in Taiwan from 1995 to 2008. Propensity score matching and Cox proportional hazards regression models were used to estimate hazard ratios for new-onset AF. Among 113,186 patients, 13% received ACEIs, 14% received ARBs therapy, and 9% received ACEIs or ARBs alternatively. After a median follow-up of 1524 days, the incidence of new-onset AF significantly decreased in patients treated with ACEIs (hazard ratio 0.587, 95% confidence interval 0.519-0.663), ARBs (0.542, 0.461-0.637), or ACEIs/ARBs (0.793, 0.657-0.958). The prevention of new-onset AF was significantly better in patients taking longer duration of ACEI or ARB therapy. The effect remained robust in subgroup analyses. Thus both ACEIs and ARBs appear to be effective in the primary prevention of AF in patients with ESRD. Hence, renin-angiotensin system inhibition may be an emerging treatment target for the primary prevention of AF.

    The cardiothoracic ratio (CTR) is a non-invasive left ventricular hypertrophy index. However, whether CTR associates with cardiovascular disease (CVD) and mortality in hemodialysis (HD) populations is unclear. Using a Mineral and Bone disorder Outcomes Study for Japanese CKD Stage 5D Patients (MBD-5D Study) subcohort, 2266 prevalent HD patients (age 62.8 years, female 38.0%, HD duration 9.4 years) with secondary hyperparathyroidism (SHPT) whose baseline CTR had been recorded were selected. We evaluated associations between CTR and all-cause death, CVD death, or composite events in HD patients. CTR was associated significantly with various background and laboratory characteristics. All-cause death, CVD-related death, and composite events increased across the CTR quartiles (Q). Adjusted hazard risk (HR) for all-cause death was 1.4 (95% confidential interval, 0.9-2.1) in Q2, 1.9 (1.3-2.9) in Q3, and 2.6 (1.7-4.0) in Q4, respectively (Q1 as a reference). The corresponding adjusted HR for CVD-related death was 1.8 (0.8-4.2), 3.1 (1.4-6.8), and 3.5 (1.6-7.9), and that for composite outcome was 1.2 (1.0-1.6), 1.7 (1.3-2.2), and 1.8 (1.5-2.3), respectively. Exploratory analysis revealed that there were relationships between CTR and age, sex, body mass index, comorbidity of CVD, dialysis duration, dialysate calcium level and intact parathyroid hormone, phosphorus, hemoglobin, and usage of phosphate binder. CTR correlated with all-cause death, CVD death, and composite events in HD patients with SHPT.

    Aim: To demonstrate the value of pelvic magnetic resonance imaging (MRI) in mapping tumour extension after chemoradiotherapy and before anterior pelvic exenteration in patients with primary carcinoma of the urethra. Materials and methods: The Institutional Review Board approved and issued a waiver of informed consent for this retrospective study, which was compliant with the Health Insurance Portability and Accountability Act. Six women (median age 51 years, range 39-63 years) with histopathology-proven urethral carcinoma who underwent neoadjuvant chemoradiotherapy before anterior pelvic exenteration were included in the study. All had MRI performed at first presentation and after completion of chemoradiotherapy. MRI images were analysed by an experienced reader, who was blinded to the clinical data. The tumour location, signal intensity, size, local extension, and presence of enlarged lymph nodes were recorded for each patient at baseline and after chemoradiotherapy. Surgical histopathology constituted the reference standard. Results: All tumours were locally advanced (stage T3) at baseline MRI. The mean maximum diameter of the tumour at baseline MRI was 3.7 cm (range 2.4-5 cm). After chemoradiotherapy, the mean reduction in maximum tumour diameter on MRI was 44% (range 13-67%), but only three cases were down-staged. MRI was accurate in the evaluation of tumour extension after completion of chemoradiotherapy in all cases. Persistence of bladder neck and anterior vaginal wall invasion was correctly identified in three cases. Conclusion: In women with advanced primary urethral cancer, MRI is an excellent tool for monitoring neo-adjuvant chemoradiotherapy changes and evaluating the extent of disease before exenterative surgery.

    We tested the hypothesis that causality analysis, applied to the spontaneous beat-to-beat variability of heart period (HP) and systolic arterial pressure (SAP), can identify the improvement of autonomic control linked to plantar mechanical stimulation in patients with Parkinson's disease (PD). A causality index, measuring the strength of the association from SAP to HP variability, and derived according to the Granger paradigm (i.e. SAP causes HP if the inclusion of SAP into the set of signals utilized to describe cardiovascular interactions improves the prediction of HP series), was calculated using both linear model-based (MB) and nonlinear model-free (MF) approaches. Univariate HP and SAP variability indices in time and frequency domains, and bivariate descriptors of the HP-SAP variability interactions were computed as well. We studied ten PD patients (age range: 57-78 years; Hoehn-Yahr scale: 2-3; six males, four females) without orthostatic hypotension or symptoms of orthostatic intolerance and 'on-time' according to their habitual pharmacological treatment. PD patients underwent recordings at rest in a supine position and during a head-up tilt before, and 24 h after, mechanical stimulation was applied to the plantar surface of both feet. The MF causality analysis indicated a greater involvement of baroreflex in regulating HP-SAP variability interactions after mechanical stimulation. Remarkably, MB causality and more traditional univariate or bivariate techniques could not detect changes in cardiovascular regulation after mechanical stimulation, thus stressing the importance of accounting for nonlinear dynamics in PD patients. Due to the higher statistical power of MF causality we suggest its exploitation to monitor the baroreflex control improvement in PD patients, and we encourage the clinical application of the Granger causality approach to evaluate the modification of the autonomic control in relation to the application of a pharmacological treatment, a

    To estimate the rate and predictors of surgical site infection (SSI) after hysterectomy performed for benign indications and to identify any association between SSI and other postoperative complications. Retrospective cohort study (Canadian Task Force classification II-2). National Surgical Quality Improvement Program data. Women who underwent abdominal or laparoscopic hysterectomy performed for benign indications from 2005 to 2011. Univariable and multivariable logistic regression analyses were used to identify predictors of SSI and its association with other postoperative complications. Odds ratios were adjusted for patient demographic data, comorbidities, preoperative laboratory values, and operative factors. Of 28 366 patients, 758 (3%) were diagnosed with SSI. SSI occurred more often after abdominal than laparoscopic hysterectomy (4% vs 2%; p hysterectomy, predictors of SSI included diabetes, smoking, respiratory comorbidities, overweight or obesity, American Society of Anesthesiologists class ≥ 3, perioperative blood transfusion, and operative time >180 minutes. Among those who underwent laparoscopic hysterectomy, predictors of SSI included perioperative blood transfusion, operative time >180 minutes, serum creatinine concentration ≥ 2 mg/dL, and platelet count ≥ 350 000 cells/mL(3). For patients with deep or organ/space SSI, significant predictors included perioperative blood transfusion and American Society of Anesthesiologists class ≥ 3 for abdominal hysterectomy, and non-white race, renal comorbidities, preoperative or perioperative blood transfusion, and operative time >180 minutes for laparoscopic hysterectomy. SSI was associated with longer hospital stay and higher rates of repeat operation, sepsis, renal failure, and wound dehiscence. SSI was not associated with increased 30-day mortality. SSI occurred more often after abdominal hysterectomy than laparoscopic hysterectomy performed to treat benign gynecologic disease. SSI was associated with

    This collaboration between the American College of Rheumatology and the American Association of Hip and Knee Surgeons developed an evidence-based guideline for the perioperative management of antirheumatic drug therapy for adults with rheumatoid arthritis (RA), spondyloarthritis (SpA) including ankylosing spondylitis and psoriatic arthritis, juvenile idiopathic arthritis (JIA), or systemic lupus erythematosus (SLE) undergoing elective total hip (THA) or total knee arthroplasty (TKA). A panel of rheumatologists, orthopedic surgeons specializing in hip and knee arthroplasty, and methodologists was convened to construct the key clinical questions to be answered in the guideline. A multi-step systematic literature review was then conducted, from which evidence was synthesized for continuing versus withholding antirheumatic drug therapy and for optimal glucocorticoid management in the perioperative period. A Patient Panel was convened to determine patient values and preferences, and the Grading of Recommendations Assessment, Development and Evaluation methodology was used to rate the quality of evidence and the strength of recommendations, using a group consensus process through a convened Voting Panel of rheumatologists and orthopedic surgeons. The strength of the recommendation reflects the degree of certainty that benefits outweigh harms of the intervention, or vice versa, considering the quality of available evidence and the variability in patient values and preferences. The guideline addresses the perioperative use of antirheumatic drug therapy including traditional disease-modifying antirheumatic drugs, biologic agents, tofacitinib, and glucocorticoids in adults with RA, SpA, JIA, or SLE who are undergoing elective THA or TKA. It provides recommendations regarding when to continue, when to withhold, and when to restart these medications, and the optimal perioperative dosing of glucocorticoids. The guideline includes 7 recommendations, all of which are conditional

    Deep brain stimulation (DBS) is a form of biotechnological surgery which has had considerable success for the motor improvement of Parkinson's disease and related disorders. Paradoxically, this observed motor improvement is not matched with improved psychosocial adjustment. This study contributes to a small but growing body of research aiming to understand this paradox. We conclude by discussing these aspects from a phenomenological and health psychology understanding of decision-making, human affectivity, and embodiment. A hermeneutic phenomenological case study. Semi-structured interviews with one woman with Parkinson's disease were carried out paying particular attention to (1) how the decision to have the procedure was made and (2) the affective experience in the time periods immediately prior to the procedure, shortly after and 1 month later. The thematic structure derived from the hermeneutic phenomenological analysis comprises the following experiential aspects: Making the decision: 'I was feeling rather at a dead end with my Parkinson's'; Shifting emotions and feelings: 'Terrified, excited, disappointed, overjoyed'; Embodied meaning: 'This extraordinary procedure where they were going to drill holes in my head'. This research has elucidated the complexity of decision-making, the emotional landscape, and specific bodily nature of the experience of DBS. It has suggested implications for practice informed by both existential-phenomenological theory and health psychology. Statement of contribution What is already known on this subject? Deep brain stimulation (DBS) is a newly developed form of biotechnological surgery and research indicates a mismatch between motor success and psychosocial adjustment. Most studies focuses on life post-DBS and there is relatively little research on how people make the decision to have the procedure, what their experience is of undergoing it including its emotional aspects. What does this study add? This study demonstrates that

    Chronic obstructive pulmonary disease (COPD) may increase the risk of postoperative complications and thus mortality after colorectal cancer (CRC) surgery, but the evidence is sparse. We conducted this nationwide population-based cohort study in Denmark, including all patients undergoing CRC surgery in the period 2005-2011, identified through medical databases. We categorised the patients according to the history of COPD. We assessed the rate of complications within 30 days. We computed 30-day mortality among patients with/without COPD using the Kaplan-Meier method. We used Cox regression to compute HRs for death, controlling for age, gender, type of admission, cancer stage, hospital volume, alcohol-related diseases, obesity and Charlson comorbidity score. We identified 18 302 CRC surgery patients. Of these, 7.9% had a prior diagnosis of COPD. Among patients with COPD, 16.1% were admitted postoperatively to the intensive care unit, 1.9% were treated with mechanical ventilation, and 3.6% were treated with non-invasive ventilation. In patients without COPD, the corresponding proportions were 9.7%, 1.1% and 1.1%. The reoperation rate was 10.6% among patients with COPD and 8% among patients with cancer without COPD. 30-day mortality was 13% (95% CI 11.4% to 14.9%) among patients with COPD and 5.3% (95% CI 5.0% to 5.7%) among patients without COPD, corresponding to an adjusted HR of 1.7 (95% CI 1.5 to 2.0). COPD is a strong predictor for intensive care unit admission and mortality after CRC surgery.

    Objective Prior studies examining coronary atherosclerosis in the young have been limited by retrospective analyses in small cohorts. We examined the relationship between cardiovascular risk factors (RFs) and prevalence and severity of coronary atherosclerosis in a large, prospective, multinational registry of consecutive young individuals undergoing coronary computerized tomographic angiography (CCTA). Method and results Of 27 125 patients undergoing CCTA, 1635 young (<45 years) individuals without known coronary artery disease (CAD) or coronary anomalies were identified. Coronary plaque was assessed for any CAD, obstructive CAD (≥50% stenosis), and presence of calcified plaque (CP) and non-calcified plaque (NCP). Among 1635 subjects (70% men, age 38 ± 6 years), any CAD, obstructive CAD, CP, and NCP were observed in 19, 4, 5, and 8%, respectively. Compared with women, men demonstrated higher rates of any CAD (21 vs. 12%, P < 0.001), CP (6 vs. 3%, P = 0.01), and NCP (9 vs. 5%, P = 0.008), although no difference was observed for rates of obstructive CAD (5 vs. 4%, P = 0.46). Any CAD, obstructive CAD, and NCP were higher for young individuals with diabetes, hypertension, dyslipidaemia, current smoking, or family history of CAD; while only diabetes and dyslipidaemia were associated with CP. Increasing cardiovascular RFs was associated with a greater prevalence and extent and severity of CAD, with individuals with 0, 1, 2, ≥3 RFs manifesting a dose–response increase in any CAD (P < 0.001, for trend), obstructive CAD (P < 0.001, for trend), NCP (P < 0.001, for trend), and CP (P < 0.001, for trend). In multivariable analysis adjusting for sex and cardiovascular RFs, male sex was the strongest predictor for any CAD (odds ratio [OR] = 1.95, 95% confidence interval [CI] = 1.43–2.66, P < 0.001), CP (OR = 1.46, 95% CI = 1.08–1.98, P = 0.01), and NCP (OR = 1.33, 95% CI = 1.06–1.67, P = 0.01); family history of CAD was the strongest predictor for obstructive CAD

    atherosclerotic disease as the main cause of death. Inflammation and endothelial dysfunction are directly associated with atherosclerosis. Furthermore, the infection resulting from hepatitis C virus, common among such patients, would be another worsening factor of the inflammatory state. Increased levels of endothelial dysfunction markers are found in chronic renal disease and hepatitis C, which could be important markers of atherosclerosis among these subjects. OBJECTIVE: To compare endothelial activity in patients undergoing hemodialysis with and without hepatitis C. METHODOLOGY: We selected 28 patients undergoing hemodialysis and classified them into two groups: 1-HCV(+: 18 patients (anti-HCV[+] and PCR[+] and 2-HCV(-: 10 patients (anti-HCV[-]. Before the first weekly dialysis, blood samples from both groups were collected for ICAM-1, VEGF, ALT and TAP serum dosage. RESULTS: ICAM-1 levels were high in 60.71%. The highest levels were found in HCV(+ group, though not statistically significant (p = 0.2024. There was no correlation between ICAM-1 levels and the hemodialysis time or ALT levels in any group. On the other hand, VEGF levels were normal in 92.85%. Only two patients HCV(+ had high levels. There was also no correlation between VEGF levels and the dialysis time or ALT levels. CONCLUSION: Patients undergoing hemodialysis have high endothelial lesion, nevertheless, the presence of HCV chronic infection did not prove to be an aggravating factor. This result may be due to the small number of patients, hence further analyses with a larger sample are required for definitive conclusions.

    In patients with head and neck and esophageal tumors, nutritional status may deteriorate during concurrent chemoradiotherapy (CRT). The aim of this study was to investigate the influence of enteral nutrition enriched with eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) on body composition and nutritional and functional status. In a controlled, randomized, prospective, double-blind, multicenter study, 111 patients with head and neck and esophageal cancer undergoing concurrent CRT received either an enteral standard nutrition (control group) or disease-specific enteral nutrition Supportan®-containing EPA+DHA (experimental group) via percutaneous endoscopic gastrostomy. The primary endpoint was the change of body cell mass (BCM) following CRT at weeks 7 and 14 compared with the baseline value. Secondary endpoints were additional parameters of body composition, anthropometric parameters, and nutritional and functional status. The primary endpoint of the study, improvement in BCM, reached borderline statistical significance. Following CRT, patients with experimental nutrition lost only 0.82 ± 0.64 kg of BCM compared with 2.82 ± 0.77 kg in the control group (P = .055). The objectively measured nutritional parameters, such as body weight and fat-free mass, showed a tendency toward improvement, but the differences were not significant. The subjective parameters, in particular the Kondrup score (P = .0165) and the subjective global assessment score (P = .0065) after follow-up improved significantly in the experimental group, compared with the control group. Both enteral regimens were safe and well tolerated. Enteral nutrition with EPA and DHA may be advantageous in patients with head and neck or esophageal cancer by improving parameters of nutritional and functional status during CRT. © 2013 American Cancer Society.

    Target-lesion revascularization (TLR) and loss of patency remain high following treatment of in-stent restenosis (ISR) of the femoropopliteal (FP) artery. Excimer laser atherectomy (ELA) is effective in reducing TLR and improves patency at 6-month and 1-year follow-up when compared with balloon angioplasty (PTA). The long-term sustainability of these early results is unknown. We present a retrospective analysis from our center on the 5-year outcomes of ELA in the treatment of ISR of the FP arteries. Patients who underwent ELA for FP-ISR from February 2005 to April 2010 at a single medical center were included. Demographics, angiographic and procedural variables were included. Major adverse events and 5-year TLR and target-vessel revascularization were obtained from medical records. Descriptive analysis was performed on all variables. Kaplan-Meier survival curves for TLR were plotted censored for death among patients who died before the occurrence of a TLR. Forty consecutive patients (mean age, 67.2 ± 9.0 years; 57.5% males) were included. Angiographic variables included: lesion length, 210.4 ± 104.0 mm; lesion severity, 93.9 ± 8.9%; and number of vessel runoffs, 1.7 ± 1.0. All patients were treated with adjunctive PTA. Acute procedural success was achieved in 92.5% of vessels. Distal embolization requiring treatment was 2.5%. No unplanned amputation occurred. Total deaths occurred in 8/40 (20%). At 5-year follow-up, TLR occurred in 62.5% with the steepest decline in freedom from TLR occurred in the first year followed by a less decline in the subsequent 2 to 3 years. ELA for FP-ISR continues to show progressive increase in TLR up to 5-year follow-up, but mostly occurs in the first 3 years after index procedure. These data suggest that a minimum follow-up of 3 years is needed to determine stability of treatment of FP-ISR with laser.

    Purpose: Paclitaxel-coated balloon catheters inhibit restenosis after coronary and peripheral angioplasty (PCI,PTA). The aim of this study was to investigate paclitaxel plasma levels and laboratory parameters following PTA with paclitaxel-coated balloons (PCB) in peripheral arteries. Materials and Methods: This single treatment arm, multicenter study included 14 patients with Rutherford stage 1 - 5 with occlusions of up to 5 cm or {>=} 70 % diameter stenosis of the superficial femoral or popliteal arteries (SFA, PA). PTA was performed using up to three PCB catheters. The paclitaxel plasma levels and safety laboratory parameters were determined by collecting blood samples pre-intervention, immediately post-intervention, at 0.5, 1, 2, 4, 8, 24 hours and 1 and 4 weeks post-intervention (p. i.). Vital signs were monitored to assess clinical safety. Results: PTA was performed successfully in all patients. Paclitaxel plasma levels were always below a level and duration known to cause systemic side effects. A mean peak paclitaxel plasma level (40 ng/ml) was reached immediately p. i. and decreased rapidly below detectable levels in more than half of the patients already 2 hours p. i. The paclitaxel plasma concentrations returned to values below detectable levels at 24 hours p. i. in all patients. Laboratory parameters and vital signs did not give any reason for safety concerns. No adverse events associated with balloon coating were observed. Conclusion: The results of 14 patients with peripheral arterial occlusive disease show no systemic bioavailability of paclitaxel > 24 hours after PTA with one or more PCB catheters, indicating that the PCB catheter is safe with regard to possible systemic effects.

    Alcohol dependence is a major public health problem worldwide. Brain and behavioral disruptions including changes in cognitive abilities are common features of alcohol addiction. Thus, the present study was aimed to investigate spatial learning and memory in 29 alcoholic men undergoing alcohol detoxification by using a virtual Morris maze task. As age-matched controls we recruited 29 men among occasional drinkers without history of alcohol dependence and/or alcohol related diseases and with a negative blood alcohol level at the time of testing. We found that the responses to the virtual Morris maze are impaired in men undergoing alcohol detoxification. Notably they showed increased latencies in the first movement during the trials, increased latencies in retrieving the hidden platform and increased latencies in reaching the visible platform. These findings were associated with reduced swimming time in the target quadrant of the pool where the platform had been during the 4 hidden platform trials of the learning phase compared to controls. Such increasing latency responses may suggest motor control, attentional and motivational deficits due to alcohol detoxification.

    There is a paucity of data on the temporal trends of cardiovascular risk factors in patients undergoing percutaneous coronary intervention (PCI). We investigated the secular trends of risk profiles of patients undergoing PCI without prior history of cardiovascular disease (CVD). CVD risk factors are changed over time. This time-trend analysis from 1994 to 2010 was performed within the Mayo Clinic PCI Registry. Outcome measures were prevalence of CVD risk factors, including the Framingham risk score (FRS), at the time of admission for PCI. During this period, 12,055 patients without a history of CVD (mean age, 65.0 ± 12.4 years, 67% male) underwent PCI at the Mayo Clinic. Age distribution slightly shifted toward older age (P for trend trend trend trend trend <0.001), whereas smoking prevalence did not change. The current study demonstrates that although traditional FRS and its associated predicted 10-year cardiovascular risk declined over time, the prevalence of risk factors increased in patients undergoing PCI. The study suggests the need for a new risk-factor assessment in this patient population. © 2014 Wiley Periodicals, Inc.

    Prospective controlled clinical study on low back pain (LBP). To investigate the possible effects of radiographic and other related parameters on LBP in patients underwent decompression and posterolateral instrumented fusion for degenerative lumbar spine disease. Sagittal balance of the spine after spine surgery has gained increasing interest regarding its correlation with LBP and fusion rate. To our knowledge, no advanced statistical analysis on the effects of sagittal roentgenographic and other parameters on LBP after lumbar surgery has been published. Forty-five patients with an average age of 63 years, who underwent pedicle-screw fixation in 2, 3, and 4 vertebrae for degenerative lumbar spine disease were selected to be included in this study. Radiographic and self-assessment (bodily pain, short form-36) data were evaluated using advanced statistics (multifactorial analysis) to investigate all possible correlations between a dependent parameter (LBP) and independent parameters (sex, extension of instrumentation, sagittal spinal balance, and angular motion at the adjacent free level above instrumentation). All patients were observed for an average of 5.5 years (range, 5-7 years). Male patients showed significantly more improvement of LBP than female counterparts (P = 0.024). LBP improved after surgery by the first year (P spine disease.This research suggests that the methods directed at the improvement in sagittal spinal balance of the lumbar spine, careful selection of fusion levels, and improvement of fusion rate might be beneficial for decreasing LBP after surgery in degenerative lumbar spine disease.

    The aim of this study was to evaluate and compare the Child-Turcotte-Pugh (CTP) classification system and the model for end-stage liver disease (MELD) score in predicting the severity of the systemic inflammatory response in living-donor liver transplantation patients. Recipients of liver graft were allocated to a recipient group (n = 39) and healthy donors to a donor group (n = 42). The association between the CTP classification, the MELD scores and perioperative cytokine concentrations in the recipient group was evaluated. The pro-inflammatory cytokines measured included interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α; the anti-inflammatory cytokines measured included IL-10 and IL-4. Cytokine concentrations were quantified using sandwich enzyme-linked immunoassays. The IL-6, TNF-α, and IL-10 concentrations in the recipient group were significantly higher than those in healthy donor group patients. All preoperative cytokine levels, except IL-6, increased in relation to the severity of liver disease, as measured by the CTP classification. Additionally, all cytokine levels, except IL-6, were significantly correlated preoperatively with MELD scores. However, the correlations diminished during the intraoperative period. The CTP classification and the MELD score are equally reliable in predicting the severity of the systemic inflammatory response, but only during the preoperative period.

    The study sought to compare clinical outcomes in a contemporary acute coronary syndrome (ACS) percutaneous coronary intervention (PCI) cohort stratified by chronic kidney disease (CKD) status. Patients with CKD exhibit high risks for both thrombotic and bleeding events, thus complicating decision making regarding antiplatelet therapy in the setting of ACS. The PROMETHEUS study was a multicenter observational study comparing outcomes with prasugrel versus clopidogrel in ACS PCI patients. Major adverse cardiac events (MACE) at 90 days and at 1 year were defined as a composite of death, myocardial infarction, stroke, or unplanned revascularization. Clinically significant bleeding was defined as bleeding requiring transfusion or hospitalization. Cox regression multivariable analysis was performed for adjusted associations between CKD status and clinical outcomes. Hazard ratios for prasugrel versus clopidogrel treatment were generated using propensity score stratification. The total cohort included 19,832 patients, 28.3% with and 71.7% without CKD. CKD patients were older with greater comorbidities including diabetes and multivessel disease. Prasugrel was less often prescribed to CKD versus non-CKD patients (11.0% vs. 24.0%, respectively; p < 0.001). At 1 year, CKD was associated with higher adjusted risk of MACE (1.27; 95% confidence interval: 1.18 to 1.37) and bleeding (1.46; 95% confidence interval: 1.24 to 1.73). Although unadjusted rates of 1-year MACE were lower with prasugrel versus clopidogrel in both CKD (18.3% vs. 26.5%, p < 0.001) and non-CKD (10.9% vs. 17.9%; p < 0.001) patients, associations were attenuated after propensity stratification. Similarly, unadjusted differences in 1-year bleeding with prasugrel versus clopidogrel (6.0% vs. 7.4%, p = 0.18 in CKD patients; 2.6% vs. 3.5%, p = 0.008 in non-CKD patients) were not significant after propensity score adjustment. Although risks for 1-year MACE were significantly higher in ACS PCI patients with

    To investigate the prevalence of significant renal artery stenosis (RAS ≥50%), and to identify clinical predictors for significant RAS in patients with an elevated cardiovascular risk, such as those affected by ischemic heart disease. In patients with an elevated cardio-vascular risk, both atherosclerotic renovascular disease and coronary artery disease (CAD) are likely to occur. Prospectively from April 2007 to March 2008, all consecutive patients with ischemic heart disease undergoing non-emergent cardiac catheterization were also evaluated for atherosclerotic RAS by renal arteriography. A RAS ≥50% was considered as significant. A total of 1,298 patients underwent cardiac and renal angiography. Significant RAS was found in 70 out of 1,298 patients (5.4%). The presence of peripheral vascular disease, eGFR 66 years, dyslipidemia, CAD severity and pulse pressure >52 mmHg were independent clinical predictors of significant RAS, and jointly produced a ROC AUC of 0.79 (95% CI 0.73-0.85, P < 0.001). Based on these data, a prediction rule for significant RAS was developed, and it showed an adequate predictive performance with 64% sensitivity and 82% specificity. In a large cohort of patients undergoing coronary angiography, significant RAS is a relatively rare comorbidity (5.4%). A model based on simple clinical variables may be useful for the clinical identification of high CV risk patients who may be suitable for renal arteriography at the time of cardiac catheterization.

    Left ventricular (LV) mechanical dyssynchrony (LVMD) was assessed by gated single-photon emission CT myocardial perfusion imaging (MPI) as an independent predictor of death from any cause in patients with known coronary artery disease (CAD) and reduced LV function. Between 2001 and 2010, 135 patients (64 {+-} 11 years of age, 84 % men) with known CAD, reduced LV ejection fraction (LVEF, 38 {+-} 15 %) and without an implanted cardiac resynchronization therapy device underwent gated MPI at rest. LV functional evaluation, which included phase analysis, was conducted to identify patients with LVMD. Kaplan-Meier survival curves were calculated for death of any cause during a mean follow-up of 2.0 {+-} 1.7 years. Uni- and multivariate Cox proportional hazards regression models were calculated to identify independent predictors of death from any cause. Of the 135 patients, 30 (22 %) died during follow-up (18 cardiac deaths and 12 deaths from other causes). Kaplan-Meier curves showed a significantly shorter survival time in the patients with severely reduced LVEF (<30 %, n = 45) or with LVMD (n = 81, log-rank test P <0.005). Cox models identified LVMD, LVEF <30 % and a total perfusion deficit at rest of {>=}20 % as independent predictors of death from any cause. While patients with LVEF <30 % in conjunction with LVMD had similar survival times irrespective of whether they had early revascularization or medical therapy, those patients with LVEF {>=}30% and LVMD who underwent revascularization had significantly longer survival. In patients with known CAD and reduced LV function, dyssynchrony of the LV is an independent predictor of death from any cause. (orig.)

    Full Text Available Kidney failure affects different aspects of normal life. Among different manifestations, sleep problem can be considered as a common complaint of ESRD (End Stage Renal Disease patients. In this study, we aimed to investigate the interrelationship between sleep disorders in ESRD patients and their characteristics. Through a cross-sectional study (2010-2011, 88 ESRD patients undergoing maintenance hemodialysis thrice weekly were recruited to enter the study. We used a self-administered questionnaire into which the data were reflected. The patients selected their specific sleep disorders using a nine-item scale while the Epworth Sleepiness Scale (ESS determined both the presence and severity of sleep disorders. The data was finally analyzed with their baseline characteristics, dialysis characteristics, medication/stimulants use, and clinical and biochemical parameters. Over 95% of the patients had, at least, one specific sleep disorder while the ESS revealed 36.36% of patients as normal, 59.09% as having mild sleep disorders, and 4.54% as having moderate to severe sleep disorders. Sleep disorders were significantly correlated with older ages (P=0.035, dialysis dose (P=0.001, blood creatinine levels (P=0.037, upper airways obstruction (P=0.035, hepatomegaly (P=0.006, hepatic failure (P=0.001, higher blood TSH levels (P=0.039, history of hypothyroidism (P=0.005, and the use of levodopa (P=0.004, anti-hypertensive medications (P=0.006, benzodiazepines (P=0.006, Eprex (Erythropoietin (P=0.001, Venofer (Iron Sucrose Injection (P=0.013, and phosphate-binders agents (P=0.018. Sleep disorders are common findings among ESRD patients and seem to be a more complicated issue than a simple accumulation of the wastes products in the body. Whatever the causes of sleep disorders are, disorder-specific treatments should be considered.

  1. Endovascular stents: a review of their use in peripheral arterial disease.

    Science.gov (United States)

    Kudagi, Vinod S; White, Christopher J

    2013-06-01

    Technological advances in the past decade have shifted revascularization strategies from traditional open surgical approaches toward lower-morbidity percutaneous endovascular treatments for patients with lower extremity peripheral arterial disease (PAD). The continuing advances in stent design, more than any other advances, have fueled the growth of catheter-based procedures by improving the safety, durability, and predictability of percutaneous revascularization. Although the 2007 TransAtlantic Inter-Society Consensus (TASC) guidelines recommend endovascular therapy for type A and B aortoiliac and femoropopliteal lesions, recent developments in stent technology and increased experience of interventionists have suggested that a strategy of endovascular therapy first is appropriate in experienced hands for TASC type D lesions. The role of endovascular interventions is also expanding in the treatment of limb-threatening ischemia.

We present a system for extracting disease-gene associations from biomedical abstracts. The system consists of a highly efficient dictionary-based tagger for named entity recognition...... of human genes and diseases, which we combine with a scoring scheme that takes into account co-occurrences both within and between sentences. We show that this approach is able to extract half of all manually curated associations with a false positive rate of only 0.16%. Nonetheless, text mining should...... not stand alone, but be combined with other types of evidence.

    Objectives: To evaluate the performance and efficacy of endovascular irradiation after percutaneous transluminal angioplasty (PTA) of de-novo femoropopliteal stenoses in a pilot study. Methods: 6 patients received non-centered endovascular irradiation (12 Gray at surface of the vessel wall) immediately after angioplasty of de-novo femoropopliteal stenosis, 1 patient was given centered endovascular irradiation using 192-iridium (12 Gray at surface of the vessel wall) Centered irradiation was considered for two other patients. Duplex sonographies and interviews were performed the day before and after PTA and after 1, 3, 6, 9, 12, 18, 24 months up to 4 years. Intraarterial angiography was performed in symptomatic patients. Results: Non-centered endovascular irradiation was possible in all patiens without problems or complications. Centered irradiation was not possible in two patients with the cross-over approach. One thromboembolic complication occurred during centered irradiation. Both restenosis and new stenosis at the edge of irradiated distance occurred in 1/7 patiens. No other side effects were observed during follow-up. Conclusions: In our pilot study endovascular irradiation after angioplasty of de-novo femoropopliteal stenosis was possible with low rates of complications and restenosis and taking vessel anatomy into account.

    Aims To date, the therapeutic benefit of revascularization vs. medical therapy for stable individuals undergoing invasive coronary angiography (ICA) based upon coronary computed tomographic angiography (CCTA) findings has not been examined. Methods and results We examined 15 223 patients without known coronary artery disease (CAD) undergoing CCTA from eight sites and six countries who were followed for median 2.1 years (interquartile range 1.4–3.3 years) for an endpoint of all-cause mortality. Obstructive CAD by CCTA was defined as a ≥50% luminal diameter stenosis in a major coronary artery. Patients were categorized as having high-risk CAD vs. non-high-risk CAD, with the former including patients with at least obstructive two-vessel CAD with proximal left anterior descending artery involvement, three-vessel CAD, and left main CAD. Death occurred in 185 (1.2%) patients. Patients were categorized into two treatment groups: revascularization (n = 1103; 2.2% mortality) and medical therapy (n = 14 120, 1.1% mortality). To account for non-randomized referral to revascularization, we created a propensity score developed by logistic regression to identify variables that influenced the decision to refer to revascularization. Within this model (C index 0.92, χ2 = 1248, P < 0.0001), obstructive CAD was the most influential factor for referral, followed by an interaction of obstructive CAD with pre-test likelihood of CAD (P = 0.0344). Within CCTA CAD groups, rates of revascularization increased from 3.8% for non-high-risk CAD to 51.2% high-risk CAD. In multivariable models, when compared with medical therapy, revascularization was associated with a survival advantage for patients with high-risk CAD [hazards ratio (HR) 0.38, 95% confidence interval 0.18–0.83], with no difference in survival for patients with non-high-risk CAD (HR 3.24, 95% CI 0.76–13.89) (P-value for interaction = 0.03). Conclusion In an intermediate-term follow-up, coronary revascularization is

    Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits). Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

    Objective To assess the value of SYNTAX score and Global Risk Classification ( GRC ) in predicting major adverse cardiac and cerebrovascular events ( MACCE ) among patients with three - vessel and/or left - main coronary artery disease undergoing percutaneous coronary intervention ( PCI ) and furthermore compare the predictive ability between the two models. Methods A total of 190 patients with three - vessel and/or left - main coronary artery disease undergoing PCI with Cypher - select drug - eluting stent in Cardiology Department of Beijing Anzhen Hospital between January 2007 to December 2008 were enrolled. SYNTAX score and GRC were retrospectively calculated according to the angiography result. The clinical end-point focused on MACCE , including death, nonfatal myocardial infarction ( MI ), stroke, and repeat revascularization. Follow-up was carried out by telephone or outpatient interview. The value of SYNTAX score and GRC to predict MACCE were studied respectively. Furthermore, area under the curve ( AUC ) was calculated to assess the difference between the predictive ablity of SYNTAX score and GRC. Results MACCE rates of low, intermediate, and high tertiles according to SYNTAX score were 9. 1% , 16. 2% and 30. 9% , respectively. Both univariate analysis and multivariate analysis showed that SYNTAX score was the independent predictor of MACCE [HR=2. 15, 95% CI (1.30, 3.54), P= 0.003; HR =2. 07, 95% CI (1.25, 3.44), P = 0.005] . MACCE rates of low, intermediate, and high tertiles according to GRC were 17. 8% , 14. 2% and 46. 1% , respectively. Both univariate analysis and multivariate analysis showed that GRC was the independent predictor of MACCE [ HR = 1. 94, 95% CI ( 1. 22, 3. 50 ), P = 0. 007; HR = 1. 94, 95% CI ( 1. 15, 3. 27 ), P = 0. 013 ] . AUC of SYNTAX score was 0. 667 [ 95% CI ( 0. 564, 0. 770 ), P = 0. 004 ], and AUC of GRC was 0. 617 [ 95% CI ( 0. 512, 0. 736 ), P = 0. 046 ] .

    Infection with hepatitis C virus (HCV) is increasing all over the world, especially among hemodialysis patients. HCV is one of the major autoantibody inducing viruses, where anti-nuclear antibodies (ANA), anti-smooth muscle antibodies (ASMA), anti-liver kidney microsome antibodies (LKM-1), and rheumatoid factor (RF) have been related to HCV. Few studies have investigated the presence of anti-extractable nuclear antigens (ENA) antibodies in chronic liver diseases, especially in chronic hepatitis C cases, but none investigated its immunostimulation role in hemodialysis units. The aim of the study was to assess the prevalence of HCV among chronic kidney disease- Stage 5 (CKD5) patients undergoing hemodialysis and the prevalence of ENA antibodies among them. Sera of 134 patients with chronic kidney disease undergoing hemodialysis, were screened for HCV antibodies and ENA antibodies profile, using ELISA and Immunoblot technique. 41 HCV-positive blood bank donors were used as controls. Sixty-four (47.7%) of 134 patients undergoing hemodialysis were infected with HCV. Thirty-three (51.6%) of 64 patients with HCV infection undergoing hemodialysis had anti-ENA antibodies: 9 (27.3%) showed anti-SSA antibodies and 22 (66.7%) had anti-SSB antibodies. The prevalence of anti-ENA antibodies was significantly higher in the patients with HCV infection, undergoing hemodialysis, compared with both control groups (hepatitis C-positive blood bank donors and hepatitis C-negative patients undergoing hemodialysis). Seventeen of 33 HCV antibodies-positive males undergoing hemodialysis had anti-ENA antibodies, compared with 16 of 31 females, indicating no sex related difference. This study emphasizes the high prevalence of HCV infection in our hemodialysis patients, comparable to that of other Middle Eastern countries, but higher than Western ones. A strong association was observed between anti-HCV positivity and hemodialysis duration, as well as anti-ENA antibody profile. However, these

    The US Nuclear Regulatory Commission's (NRC's) Office of Inspection and Enforcement (IE) has conducted direct inspections (integrated design inspections) of the technical aspects of the nuclear plant design process for several plants under construction. It has also evaluated independent design verification programs and engineering assurance programs at a number of other plants under construction. Many of the lessons learned from these construction phase efforts are directly applicable to operating plants undergoing major modifications. This has been confirmed by IE direct inspections of the design aspects of safety systems outage modifications, which have identified significant potential safety-related deficiencies. The paper discusses methodology for design inspections; failure to maintain up-to-date design basis documentation; and lessons learned common to plants under construction and undergoing major modifications.

    BACKGROUND: There is substantial variability in the perioperative administration of aspirin in patients undergoing noncardiac surgery, both among patients who are already on an aspirin regimen and among those who are not. METHODS: Using a 2-by-2 factorial trial design, we randomly assigned 10......,010 patients who were preparing to undergo noncardiac surgery and were at risk for vascular complications to receive aspirin or placebo and clonidine or placebo. The results of the aspirin trial are reported here. The patients were stratified according to whether they had not been taking aspirin before...... the study (initiation stratum, with 5628 patients) or they were already on an aspirin regimen (continuation stratum, with 4382 patients). Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum...

    Peripheral artery disease (PAD) typically refers to lower limb vessel ischemia caused by atherosclerotic stenosis of lower extremity arteries. IL18 is a pleiotropic pro-inflammatory cytokine reported to function as an inflammatory biomarker in cardiovascular diseases. IL18 activity is balanced by high-affinity naturally occurring IL18-binding protein (IL18BP). This study aimed to determine whether IL18, IL18 BP mRNA levels and -137 G/C (rs187238) polymorphism, which was previously associated with IL18 gene transcriptional activity, were associated with PAD etiology. IL18, IL18BP mRNA levels from peripheral blood mononuclear cells and -137 G/C (rs187238) polymorphism were determined by quantitative real-time polymerase chain reaction (qRT-PCR) and RT-PCR, respectively, in 55 PAD patients (26 aorta-iliac, 29 femoro-popliteal) and 61 disease-free controls. IL18 mRNA levels were increased in PAD patients compared with healthy controls (p = 0.09); however, did not reach a statistical significant level, also did not significantly differ between aorta-iliac and femoro-popliteal occlusive PAD subgroups (p = 0.285). However, IL18BP mRNA levels were significantly lower in PAD group compared with controls (p triglycerides and LDL cholesterol levels in PAD patients (p = 0.003, p = 0.014, respectively). HDL cholesterol levels were negatively correlated with IL18 mRNA levels in controls (p = 0.05). This report is a preliminary study to show an association between IL18, IL18BP mRNA levels and PAD and suggests that the IL18 gene may have a significant relationship with triglyceride and LDL cholesterol levels in PAD patients.

    Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

    To analyze perceived health status and other health-related indicators in the adult population in Granada (Spain) undergoing an eviction process from their homes, whether rented or owned, in comparison with health indicators in the general adult population in Andalusia. A cross-sectional survey was administered by trained staff. The survey included instruments from the Andalusian Health Survey 2011 for measuring variables related to physical and mental health, as well as health-related habits. We compared the results with those obtained from the Andalusian general population through the Andalusian Health Survey. A bivariate analysis using the χ2 test and a multivariate logistic regression analysis were conducted. We obtained a total sample of 205 people in the process of eviction. A total of 59.5% (n=122) were women, and 40.5% (n=83) were men. Participants were more likely to have poor health (odds ratio [OR]: 12.63, 95% confidence interval [95%CI]: 8.74-18.27), have cardiovascular diseases (OR: 3.08; 95%CI: 1.54- 6.16), or to smoke (OR: 1.68; 95% CI: 1.21-2.33) compared with the Andalusian general population. Most of the health indicators analyzed showed a worse outcome for women undergoing an eviction process. Our results suggest that, in the current context of economic crisis, people undergoing a process of eviction in Granada and its metropolitan area show poorer health than the Andalusian general population. Further research is needed on health and evictions from different methodological approaches, for a better understanding of the topic. Copyright © 2015 SESPAS. Published by Elsevier Espana.

    Reduction of cognitive function is a possible side effect after the use of cardiopulmonary bypass (CPB) during cardiac surgery. Since it has been proven that piracetam is cerebroprotective in patients undergoing coronary bypass surgery, we investigated the effects of piracetam on the cognitive performance of patients undergoing open heart surgery. Patients scheduled for elective open heart surgery were randomized to the piracetam or placebo group in a double-blind study. Patients received 12 g of piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on day 3, postoperatively. To assess the overall cognitive function and the degree of cognitive decline across all tests after the surgery, we combined the six test-scores by principal component analysis. A total of 88 patients with a mean age of 67 years were enrolled into the study. The mean duration of CPB was 110 minutes. Preoperative clinical parameters and overall cognitive functions were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed deterioration of cognitive function in both groups (piracetam: preoperative 0.19 ± 0.97 vs. postoperative -0.97 ± 1.38, p piracetam did not perform better than those taking placebo, and both groups had the same decline of overall cognitive function (p = 0.955). Piracetam had no cerebroprotective effect in patients undergoing open heart surgery. Unlike the patients who underwent coronary surgery, piracetam did not reduce the early postoperative decline of neuropsychological abilities in heart valve patients.

    Cardiovascular disease is one of the leading causes of death in patients with advanced renal disease. The objective of this study was to investigate impairments in heart rhythm complexity in patients with end-stage renal disease. We prospectively analyzed 65 patients undergoing peritoneal dialysis (PD) without prior cardiovascular disease and 72 individuals with normal renal function as the control group. Heart rhythm analysis including complexity analysis by including detrended fractal analysis (DFA) and multiscale entropy (MSE) were performed. In linear analysis, the PD patients had a significantly lower standard deviation of normal RR intervals (SDRR) and percentage of absolute differences in normal RR intervals greater than 20 ms (pNN20). Of the nonlinear analysis indicators, scale 5, area under the MSE curve for scale 1 to 5 (area 1-5) and 6 to 20 (area 6-20) were significantly lower than those in the control group. In DFA anaylsis, both DFA α1 and DFA α2 were comparable in both groups. In receiver operating characteristic curve analysis, scale 5 had the greatest discriminatory power for two groups. In both net reclassification improvement model and integrated discrimination improvement models, MSE parameters significantly improved the discriminatory power of SDRR, pNN20, and pNN50. In conclusion, PD patients had worse cardiac complexity parameters. MSE parameters are useful to discriminate PD patients from patients with normal renal function.

    Full Text Available Presence of fixed orthodontic appliances in the mouth leads to accumulation of food debris and an elevation in the amount of plaque. It also hinders plaque removal by tooth brushing alone. Chemical agents may be used during the active phase of orthodontic treatment to reduce the bacterial plaque accumulation and decrease the occurrence of periodontal disease in these patients. The present study was therefore done to compare the efficacy of chemical plaque control by chlorhexidiene in patients undergoing orthodontic treatment. Forty five subjects for this double blind study were assigned randomly into three groups of 15 each. Gingival inflammation, plaque accumulation, and bleeding on probing, were recorded at baseline (10 days after prophylaxis, and at the end of one month in all the three groups. The data obtained was subjected to stastical analysis. Anova test showed significant difference among all the three groups for bleeding index, modified gingival index and plaque index. Paired t test showed significant differences in bleeding index for pre and post treatment recordings for chlorhexidine group. Modified gingival index showed significant difference in the chlorhexidine group. For plaque index significant difference was found for chlorhexidine, and control groups. Chlorhexidine mouthrinse 0.12% was found to be the most effective in reducing the bleeding scores, modified gingival index scores and the plaque index scores. It can therefore be said that chlorhexidine mouthrinse 0.12% provides greater benefits to the patients undergoing fixed orthodontic treatment.

    Reduction of cognitive function is a possible side effect after cardiac surgery using cardiopulmonary bypass. We investigated the cerebroprotective effect of piracetam on cognitive performance in patients undergoing coronary artery bypass surgery under cardiopulmonary bypass. Patients scheduled for elective, primary and isolated coronary bypass surgery were randomised either to piracetam or placebo group. The study was performed in a double blind fashion. Patients received either 12 g piracetam or placebo at the beginning of the operation. Six neuropsychological subtests from the Syndrom Kurz Test and the Alzheimer's Disease Assessment Scale were performed preoperatively and on the third postoperative day. To assess the overall cognitive function and the degree of cognitive decline across all tests after surgery we combined the six test-scores by principal component analysis. A total number of 120 patients were enrolled into the study. Preoperative overall cognitive function were not significantly different between the groups. The postoperative combined score of the neuropsychological tests showed a deterioration of cognitive function in both groups (placebo-pre: -0.06+/-0.99 vs placebo-post: -1.38+/-1.11; ppiracetam-pre: 0.06+/-1.02 vs piracetam-post: -0.65+/-0.93; ppiracetam patients performed significantly better compared to the placebo patients after the operation and had a less decline of overall cognitive function (pPiracetam has a cerebroprotective effect in patients undergoing coronary artery bypass surgery with the use of cardiopulmonary bypass. It reduces an early postoperative substantial decline of neuropsychological abilities.

    ón de cirugía de revascularizacion del miocárdio. Con base en antropología interpretativa, los datos fueron reunidos en informes narrativos y analizados por medio de la a elaboración de unidades de significados y núcleos temáticos. RESULTADOS:Los sentidos atribuidos a la enfermedad se relacionaron a: descubierta de la enfermedad cardiaca, sentimientos desencadenados, explicaciones formuladas, aceptación de la cirugía y vida pos-cirurgica. La experiencia fue interpretada como ruptura biográfica, situación entre la vida y la muerte, invalidez, perdida de autonomía e incapacidad de trabajar. Los significados se remitieron a una lógica que articula sentido común, religión y fragmentos del discurso médico en la comprensión de la enfermedad y de la cirugía cardiaca. CONCLUSIONES: Los resultados rebelan que las experiencias de la enfermedad y de la cirugía cardíaca marcan una ruptura en el modo de vivir, trabajar y comprender el proceso salud-enfermedad. La abordaje de la experiencia de la enfermedad cardiaca contribuye para extrapolar los límites de un modelo centrado en la enfermedad, sus síntomas y causas, característico del entendimiento biomédico del proceso salud-enfermedad, cuyo foco es el mal funcionamiento del proceso biológico y/o psicológico.OBJECTIVE:To evaluate the meanings of heart disease experience in patients undergoing rehabilitation post-coronary artery bypass grafting surgery. METHODS:Ethnographic study carried out between 2003 and 2005 in the city Goiânia, Central-West Brazil. Direct observation and in-depth interviews were conducted in 11 patients undergoing rehabilitation post- coronary artery bypass grafting surgery. Using an interpretative anthropology approach, data were gathered in narrative documents and analyzed through the identification of units of meanings and thematic groups.

La letalidad en la unidad de cuidados intensivos se presentó en 2,2% del grupo de balón y en 3% del otro grupo (p=0,06. No ocurrió mortalidad intrahospitalaria fuera de la unidad de cuidados intensivos como tampoco mortalidad a 30 días después del alta. El tiempo de estancia en la misma unidad fue de 4,13 días en el grupo de balón y 2,7 días en el grupo sin balón, sin diferencia estadísticamente significativa entre éstos (p=0,154. El tiempo de ventilación mecánica en el grupo de balón fue de 1,96 días mientras que en el otro grupo fue de 1,18 días sin diferencia estadísticamente significativa (p=0,288. Con respecto a los pacientes que recibieron balón de contra pulsación intra-aórtico, el promedio de uso de balón fue de 1,32 días y no se presentaron complicaciones vasculares relacionadas con su uso. Conclusiones: este estudio sugiere que con el uso rutinario del balón de contra pulsación aórtica previo a la cirugía electiva de revascularización coronaria en pacientes cuya única indicación sea la lesión severa del tronco común izquierdo, no se obtiene beneficio en cuanto a letalidad y tiempo de estancia en la unidad de cuidados intensivos, ni con respecto al tiempo de ventilación mecánica. Tampoco se encontró mayor riesgo de desarrollar infección o sepsis en la misma unidad.Background: Left main coronary artery disease as the only criterion for intra-aortic balloon counterpulsation implantation is an indication which evidence is limited to experts’ recommendations; therefore, studies that may give a higher level of evidence are required. For this reason, we developed in our institution a study that evaluated the experience in the use of IABP in patients with left main coronary artery disease undergoing coronary revascularization surgery.

    Full Text Available Dermatillomania is a disorder in which a person habitually picks their skin, and this is a form of self-injury. It can involve any part of the body, but usually involves the face, neck, arms and shoulders. Symptoms often follow an event that has caused severe emotional distress. A dermatillomania or compulsive skin picking episode may be a conscious response to anxiety or depression but is frequently done as an unconscious habit. In this case report, a patient undergoing orthodontic treatment was found to be suffering from dermatillomania and was treated using psychological counseling.

    2012-02-01

    Thromboprophylaxis for women undergoing caesarean section (CS) was introduced in the hospital in 1995. This study audited the use of tinzaparin prophylaxis in a nested cohort of women who screened negative for diabetes mellitus at 28 weeks gestation. All the women had their weight measured and BMI calculated at the first antenatal visit. Of the 284 women, 68 (24%) had a CS and all received tinzaparin. Of the 68, however, 94% received a dose lower than recommended. Compliance with prophylaxis was complete but compliance with the recommended dosage was suboptimal, which may result in venous thromboembolism after CS despite thromboprophylaxis.

    Oral health care in patients undergoing chemotherapy and/or radiation therapy can be complex. Care delivered by a multidisciplinary approach is timely and streamlines the allocation of resources to provide prompt care and to attain favorable outcomes. A hospital dentist, oral and maxillofacial surgeon, and a maxillofacial prosthodontist must be involved early to prevent avoidable oral complications. Prevention and thorough preparation are vital before the start of chemotherapy and radiation therapy. Oral complications must be addressed immediately and, even with the best management, can cause delays and interruption in treatment, with serious consequences for the outcome and prognosis.

    Objective To study the neuroprotective effect of sevoflurane on controlled hypotension in patients with coronary heart disease undergoing craniocerebral surgery. Methods Twenty-six patients with coronary heart disease undergoing craniocerebral surgery were randomly divided into two groups,receiving either inhaled 2%-5%sevoflurane plus intravenous sodium nitroprusside (treatment group,n=13) or intravenous sodium nitroprusside 3-8 μg·kg-1 alone (contorl group,n=13) for blood pressure control. The hemodynamic changes were recorded during the operation. Patient satisfaction with surgeons and the duration hospital stay after surgery were recorded. The levels of cardiac troponin I (TNI),creatine kinase-MB (CK-MBM),neuron specific enolase ( NSE) and S100 calcium binding proteinβ( S-100βprotein) in serum were detected at one day pre-operation,the end of the operation,and one day post-operation. Results The duration of hospital stay after surgery was significantly shortened in treatment group [(20. 3±3. 8) versus (23. 9±4. 6) d,P<0. 05) compared with control group. The average heart rate significantly decreased, patient satisfaction significantly increased, and serum levels of NSE and S-100β protein one day post-operation significantly decreased as compared to control group (all P<0. 05). Compared with the day before operation,serum levels of NSE and S-100βprotein in the two groups increased significantly at the end of surgery (P<0. 05),and the levels of TNI,CK-MBM,NSE and S-100βsignificantly elevated one day post-operation (P<0. 05). Compared with the end of operation,serum levels of NSE and S-100βin contorl group incarcerated remarkably (P<0. 05) Conclusion Sevoflurane plays an important neuroprotective role,as evidenced by improving patients' satisfaction,reducing hospital stay after surgery,and maintaining the balance of myocardial oxygen delivery and consumption in craniocerebral surgery patients with coronary heart disease during controlled hypotension

    Full Text Available INTRODUCTION: Patients undergoing hematopoietic stem cell transplantation receive high doses of chemotherapy and radiotherapy, which cause severe immunosuppression.OBJECTIVE: To report an oral disease management protocol before and after hematopoietic stem cell transplantation.METHODS: A prospective study was carried out with 65 patients aged > 18 years, with hematological diseases, who were allocated into two groups: A (allogeneic transplant, 34 patients; B (autologous transplant, 31 patients. A total of three dental status assessments were performed: in the pre-transplantation period (moment 1, one week after stem cell infusion (moment 2, and 100 days after transplantation (moment 3. In each moment, oral changes were assigned scores and classified as mild, moderate, and severe risks.RESULTS: The most frequent pathological conditions were gingivitis, pericoronitis in the third molar region, and ulcers at the third moment assessments. However, at moments 2 and 3, the most common disease was mucositis associated with toxicity from the drugs used in the immunosuppression.CONCLUSION: Mucositis accounted for the increased score and potential risk of clinical complications. Gingivitis, ulcers, and pericoronitis were other changes identified as potential risk factors for clinical complications.

    Acupuncture and related techniques have been used as adjuncts for perioperative anesthesia management. We examined whether acupressure in the Extra-1 (Yin-Tang) point would result in decreased preprocedural anxiety and reduced intraprocedural propofol requirements in a group of children undergoing endoscopic procedures. Fifty-two children were randomized to receive acupressure bead intervention either at the Extra-1 acupuncture point or at a sham point. A Bispectral Index (BIS) monitor was applied to all children before the onset of the intervention. Anxiety was assessed at baseline and before entrance to the operating room. Anesthetic techniques were standardized and maintained with IV propofol infusion titrated to keep BIS values of 40-60. We found that after the intervention, children in the Extra-1 group experienced reduced anxiety whereas children in the sham group experienced increased anxiety (-9% [-3 to -15] vs 2% [-6 to 7.4], P = 0.012). In contrast, no significant changes in BIS values were observed in the preprocedural waiting period between groups (P = ns). We also found that total intraprocedural propofol requirements did not differ between the two study groups (214 +/- 76 microg x kg(-1) x min(-1) vs 229 +/- 95 microg x kg(-1) x min(-1), P = 0.52). We conclude that acupressure bead intervention at Extra-1 acupoint reduces preprocedural anxiety in children undergoing endoscopic procedures. This intervention, however, has no impact on BIS values or intraprocedural propofol requirements.

    Lanthanum carbonate (LaC) is a non-calcium-based phosphate binder used to treat hyperphosphatemia in patients with chronic kidney disease. Oral administration of LaC is difficult in patients undergoing tube feeding or those who are of advanced age because it is essential to chew the LaC tablet sufficiently before swallowing it. We report two cases in whom crushed LaC was used in hemodialysis patients undergoing tube feeding. In both cases, previously crushed LaC was mixed into enteral nutrients. We found that LaC administered this way was effective for decreasing serum phosphorus levels.

    Objective To evaluate the correlation between multiple cardiovascular risk factors and severity of coronary heart disease (CHD) in patients undergoing coronary angiography. Methods Seven hundred and twenty eight patients who underwent coronary angiography were selected from Qilu Hospital from October 2008 to December 2009. The clinical data about cardiovascular risk factors including age, gender, hypertension, smoking status, type 2 diabetes mellitus, dyslipidemia, high uric acid level, low total bilirubin level, and coronary angiography results were collected. The severity and extent of coronary stenosis was evaluated by ACC/AHA coronary scoring system and CHD was diagnosed by angiography. Analyses were achieved by multiple regression analysis. Results Multiple regression analysis showed that age, gender, hypertension, type 2 diabetes mellitus and low HDL-C were prominent predictors of severity and extent of coronary heart disease. DM was the primary controllable risk factor of CHD (OR=3. 1179, P=0. 005). Conclusions The age, gender,hypertension, type 2 diabetes mellitus and low HDL-C are correlated with angiographic severity and extent of CHD. Consequently, controlling these five risk factors is important in the intervention and prevention of CHD.%目的 探讨心血管病危险因素与冠状动脉(冠脉)病变严重程度的相关性. 方法入选2008年10月至2009年12月在山东大学齐鲁医院行冠脉造影术的病例728例,收集其性别、年龄、吸烟史、高血压、糖尿病、总胆红素(TBIL)、血脂、尿酸等临床资料.同时收集患者冠脉造影结果,以美国心脏病学会和美国心脏协会(ACC/AHA)评分法计算冠脉病变积分,以冠脉病变积分及是否诊断为冠心病评价其冠状动脉病变程度.统计学处理采用多因素回归分析. 结果多因素回归分析结果显示,男性、年龄、高血压、糖尿病,高密度脂蛋白胆固醇这5个危险因素是影响冠脉病变积分主要的危险

    A mathematical model describing bubble dynamics in a perfused tissue undergoing decompression is presented, taking into account physical expansion and inward diffusion from surrounding supersaturated tissue as growth promoting factors and tissue gas elimination by perfusion, tissue elasticity, surface tension and inherent unsaturation as resolving driving forces. The expected behavior after a step reduction of pressure of a bubble initially existing in the tissue, displaying both growth and resolution has been demonstrated. A strong perfusion-dependence of bubble resolution time at low perfusion rates is apparent. The model can account for various exposure pressures and saturation fractions of any inert gas-tissue combination for which a set of physical and physiological parameters is available.

    Marcantoni, S.

    2017-05-01

    The thermodynamics of a qubit undergoing dephasing due to the coupling with the external environment is discussed. First of all, we assume the dynamics of the system to be described by a master equation in Lindblad form. In this framework, we review a standard formulation of the first and second law of thermodynamics that has been known in literature for a long time. After that, we explicitly model the environment with a set of quantum harmonic oscillators choosing the interaction such that the global dynamics of system and bath is analytically solvable and the Lindblad master equation is recovered in the weak-coupling limit. In this generalized setting, we can show that the correlations between system and bath play a fundamental role in the heat exchange. Moreover, the internal entropy production of the qubit is proven to be positive for arbitrary coupling strength.

    Psychological distress is a common problem among patients with cancer, yet it mostly goes unreported and untreated. This study examined the association of a psycho-educational intervention with the psychological distress levels of breast cancer and cervical cancer patients undergoing chemotherapy. The design of the study was quasi-experimental, pretest-posttest design with a comparison group. One hundred patients at a cancer hospital in Jakarta, Indonesia, completed Distress Thermometer screening before and after chemotherapy. Fifty patients in the intervention group were given a psycho-educational video with positive reappraisal, education and relaxation contents, while receiving chemotherapy. Patients who received the psycho-educational intervention had significantly lower distress levels compared with those in the control group. Routine distress screening, followed by distress management and outcome assessment, is needed to improve the wellbeing of cancer patients.

    Full Text Available Background: Patients undergoing pacemaker implantation often experience anxiety and fear. As such, studies have focused on the mechanisms that relieve the negative emotions caused by the intervention. Continuous nursing is a safe and effective nursing mode. In this study, continuous nursing intervention was provided for elderly patients undergo-ing pacemaker implantation and an empirical investigation was performed to determine the effects of their negative emotion and disease-coping ability.Methods: Overall, 114 (68 males and 46 females elderly patients who were undergoing pacemaker implantation from Harbin City (China, were enrolled in the study. The patients were divided into two groups, namely, the control group and the intervention group, based on different nursing methods. Routine nursing was applied to the control group; continuous nursing support was provided for the intervention group from January 2014 to January 2015. The nursing results of the two groups were compared. These results were also evaluated using self-rating depression scale, self-rating anxiety scale, and trait coping style questionnaire.Result: The effects of depression and anxiety intervention were significant in the intervention group (P<0.05. Com-pared with the control group, the intervention group did not significantly differ. The coping style of the intervention group elicited significant effects. Compared with the control group, the intervention group was significantly different (P < 0.05.Conclusion: Continuous nursing can relieve the negative emotion and improve the negative coping style of patients undergoing pacemaker implantation.

    The use of cell lines or animal models has significant disadvantages when dealing with a set of heterogeneous diseases such as epithelial ovarian cancer. This has clinical relevance in that biomarkers developed using cell line or animal models are often not transferable to the clinical setting. In this study, we describe the development of a robust protocol for developing primary cultures of ovarian cancer which will overcome some of these difficulties. Women undergoing surgery for ovarian cancer were recruited and samples of ascites and solid tumour deposits were used to develop primary cultures. Cells were characterised using a panel of immunofluorescent antibodies prior to use in a variety of assays including functional assessment of DNA repair pathways. During the four year study period, viable cultures, confirmed to be epithelial in origin were generated from 156 of 172 (91%) cases recruited. Characterisation was carried out using a panel of antibodies including pancytokeratin, CA125, EpCAM, MOC-31, D2-40 and vimentin. Senescence occurred between the 2nd and 8th passages in all cultures except one in which spontaneous immortalization occurred. Cells could be successfully cultured even after a period of storage at 4°C and cultured cells were capable of being used for a variety of applications including functional assays. Upon functional assessment there was minimal intra-tumour heterogeneity. It is therefore possible to derive viable ovarian cancer cell cultures in the majority of patients undergoing surgery. Cells cultured directly from patient cancers provide an accurate and highly diverse model.

  15. Acute kidney injury in patients undergoing cardiac surgery.

    The incidence of postoperative acute kidney injury (AKI) in patients undergoing cardiac surgery ranges from 7.7% to 28.1% in different studies, probably in relation to the criteria adopted to define AKI. AKI markedly increases mortality risk. However, despite the development of less invasive techniques, cardiac surgery remains the first option in many conditions such as severe coronary artery disease, valve diseases and complex interventions. The risk of postsurgery AKI can be reduced by adopting less invasive approaches, such as off-pump coronary artery bypass grafting or transcatheter aortic valve implantation, but these options cannot be employed in all cases. Thus, since traditional cardiac surgery remains the only option in many cases, it is important to adopt strategies helping the clinician to prevent AKI or diagnose it early. Old age, preprocedural chronic kidney disease, obesity, some comorbidities, wide pulse pressure and some pharmacological regimens represent risk factors for postsurgery AKI and mortality. Important intraoperative factor are use and duration of cardiopulmonary bypass. Postoperative efforts should be aimed toward maximizing cardiac output, avoiding drugs vasoconstricting the renal artery, providing adequate crystalloid infusion and alkalinizing urine. Fluid management should not be based on the measurements for cardiac filling pressures, which are mostly unreliable in these patients. Novel biomarkers such as cystatin C, kidney injury molecule-1 and human neutrophil gelatinase-associated lipocalin have been found to change earlier than creatinine, particularly when measured in combination, so their use in clinical practice can facilitate early diagnosis and treatment of AKI. The occurrence of oliguria despite adequate cardiovascular therapy can be managed with furosemide, possibly using continuous infusion, or renal replacement therapy.

    Stochastic parameterization has become commonplace in numerical weather prediction (NWP) models used for probabilistic prediction. Here, a specific stochastic parameterization will be related to the theory of stochastic differential equations and shown to be affected strongly by the choice of stochastic calculus. From an NWP perspective our focus will be on ameliorating a common trait of the ensemble distributions of tropical cyclone (TC) tracks (or position), namely that they generally contain a bias and an underestimate of the variance. With this trait in mind we present a stochastic track variance inflation parameterization. This parameterization makes use of a properly constructed stochastic advection term that follows a TC and induces its position to undergo Brownian motion. A central characteristic of Brownian motion is that its variance increases with time, which allows for an effective inflation of an ensemble's TC track variance. Using this stochastic parameterization we present a comparison of the behavior of TCs from the perspective of the stochastic calculi of Itô and Stratonovich within an operational NWP model. The central difference between these two perspectives as pertains to TCs is shown to be properly predicted by the stochastic calculus and the Itô correction. In the cases presented here these differences will manifest as overly intense TCs, which, depending on the strength of the forcing, could lead to problems with numerical stability and physical realism.

    Objective To compare the predictive values of different SYNTAX scores in patients undergoing percutaneous coronary intervention for complicated coronary artery disease. Methods SYNTAX scores were retrospectively calculated in 190 patients with three - vessel or left - main coronary artery disease from January 2007 to December 2008. Follow - up was carried out by telephone or outpatient visits. The research endpoints included major adverse cardiac or cerebrovascular events ( MACCE ), a composite of death, nonfatal myocardial infarction ( MI ), stroke, and repeat revascularization. MACCE rates according to different stratification of SYNTAX scores were recorded respectively. Cox proportional hazards model was used to calculate hazard ratios and their corresponding 95% Cis and control the confounding factors. Area under receiving operator curve ( AUROC ) were calculated to compare the predictive values of these two different stratifications. Results The MACCE rates of low ( 0 ~ 20. 5 ), intermediate ( 21. 0 ~ 31. 0 ), and high ( ≥31.5) tertiles according to SYNTAX score of our study population were 9. 1% , 16. 2% , and 30. 9% , respectively ( Log rank P = 0. 006 ), multivariable analyses [ HR = 2. 07, 95% CI (1.25, 3.44), P=0.005]; the AUROC was 0. 667 [95%CI (0.564, 0.770), P=0.004]. The MACCE rates of low (0~ 22 ), intermediate (23 ~ 32 ), and high ( ≥ 33 ) tertiles according to SYNTAX scores of SYNTAX study were 15. 7% 、 12. 9% , and 28. 6% respectively [ Log rank P =0.09, multivariable analyses HR = 1. 47, 95% CI ( 0. 94, 2. 32 ), P = 0. 10 ]; the AUROC was 0. 593 [ 95 % CI ( 0. 475, 0. 710 ), P = 0. 11 ]. Conclusion SYNTAX score tertiles according to o-verall SYNTAX score distribution of our study population ( 0 ~ 20. 5, 21. 0 ~ 31. 0, ≥ 31. 5 ) can be an independent predictor of MACCE. However, SYNTAX score tertiles according to SYNTAX study ( 0 -22, 23-32, ≥33 ) fail to predict MACCE occurrence of our study population.%目的 比较不同分层标

  18. Preoperative information needs of children undergoing tonsillectomy.

    2012-02-01

    AIMS AND OBJECTIVES: To identify the information needs of children undergoing tonsillectomy with reference to content of information, method of delivery, information providers and timing of information provision. BACKGROUND: Tonsillectomy can be anxiety provoking for children and preoperative preparation programmes are long recognised to reduce anxiety. However, few have been designed from the perspectives of children and to date little is known about how best to prepare children in terms of what to tell them, how to convey information to them, who can best provide information and what is the best timing for information provision. DESIGN: A qualitative descriptive study. METHOD: Data were collected from nine children (aged 6-9) using interviews supported by a write and draw technique. Data were coded and categorised into themes reflecting content, method, providers and timing of information. RESULTS: Children openly communicated their information needs especially on what to tell them to expect when facing a tonsillectomy. Their principal concerns were about operation procedures, experiencing \\'soreness\\' and discomfort postoperatively and parental presence. Mothers were viewed as best situated to provide them with information. Children were uncertain about what method of information and timing would be most helpful to them. CONCLUSION: Preoperative educational interventions need to take account of children\\'s information needs so that they are prepared for surgery in ways that are meaningful and relevant to them. Future research is needed in this area. RELEVANCE TO CLINICAL PRACTICE: Practical steps towards informing children about having a tonsillectomy include asking them what they need to know and addressing their queries accordingly. Child-centred information leaflets using a question and answer format could also be helpful to children.

    Children undergoing chemotherapy for cancer have special vaccination needs after completion of the treatment. The aim of this study was to evaluate the adaptation of post-chemotherapy vaccination schedules. An observational study was performed on a retrospective cohort that included all children aged from 0 to 14 years, who completed chemotherapy in a tertiary hospital between 2009 and 2015. Inclusion and exclusion criteria were applied. Immunisation was administered in accordance with the guidelines of the Vaccine Advisory Committee of the Spanish Association of Paediatrics. Primary Care immunisation and clinical records of the Preventive Medicine and Public Health Department were reviewed. Of the 99 children who had received chemotherapy, 51 (70.6% males) were included in the study. As regards the type of tumour, 54.9% had a solid organ tumour, and 45.1% had a haematological tumour. Post-chemotherapy immunisation was administered to 70.6%. The most common vaccines received were: diphtheria-tetanus-pertussis or diphtheria-tetanus (54.9%), meningococcus C (41.2%), and seasonal influenza (39.2%). The rate of adaptation of the immunisation schedule after chemotherapy was 9.8%. The pneumococcal conjugate vaccine against 7v or 13v was administered to 21.6% of study subjects. However, only 17.6% received polysaccharide 23v. None received vaccination against hepatitis A. No statistically significant differences were observed between adherence to immunisation schedules and type of tumour (P=.066), gender (P=.304), or age (P=.342). Post-chemotherapy immunisation of children with cancer is poor. The participation of health professionals in training programs and referral of paediatric cancer patients to Vaccine Units could improve the rate of schedule adaptation and proper immunisation of this population.

    The techniques, drugs and depth of sedation for flexible fiberoptic bronchoscopy is controversial, and several reports consider that the routine use of sedation is not a prerequisite. We evaluate whether the addition of sedation with propofol improves patient tolerance, compared to local anesthesic of the airway only. Eighteen patients with pneumonia undergoing flexible fiberoptic bronchoscopy were included in a randomized, single blind, prospective controlled study. The non-sedation group received airway topical anesthesia, whereas the sedation group received topical anesthesia and intravenous sedation with propofol. The degree of pain, cough, sensation of asphyxiation, degree of amnesia, global tolerance and acceptance of another bronchoscopy in the future were noted. Changes in blood pressure, heart rate and saturation of oxygen by pulse oximetry were also evaluated. The patients in sedation group had less cough (P < 0.05), pain (P < 0.01) and sensation of asphyxiation (P < 0.001). Global tolerance to the procedure was significantly better in the group under sedation (P < 0.01). These patients had total amnesia to the procedure (P < 0.0001), thus is more probable that will accept another bronchoscopy in the future (P < 0.01). There was a significant rise in heart rate and blood pressure in the patients without sedation. There were no differences in oxygen saturation (P = 0.75). Our results show that if we administer propofol for sedation, in addition to local anesthesia of the airway, the tolerance to the procedure is much better. Also it appears that sedation with propofol is safe if we carefully select and monitor the patient.

    Full Text Available In recent years, the number of patients undergoing cardiac surgeries is steadily increasing. In Greece, approximately 10,500 patients per year are admitted to some kind of cardiac operation. Constant evolution of heart surgery techniques calls for adaptation of the perioperative nursing care given. Patient education, as an important part of the perioperative care, is directly related to the reduction of postoperative complications and stress management, thus promoting the patient's overall postoperative well-being. Aim: The aim of this review was to present the most important aspects of the patient's perioperative education and the role that the nurse has to play in it. Methods: Data from selected articles were extracted from Pubmed, Chinahl and Cohrane, as well as from non-electronically published scientific studies ranging from 1998-2010 and 2003-2008 respectively. Results: According to the literature, perioperative patient education can be implemented in various ways, such as through verbal updates, the use of audiovisual means and the provision of informative leaflets. The teaching topics can be divided into those of the preoperative and postoperative phase. Stress management prepares the patients psychologically and also enhances the therapeutic nurse-patient relationship. The teaching of breathing techniques and isometric exercises of the lower limbs, the cessation of smoking, the diet to be followed, as well as the management of medication, aim in the patients' physical preparation, in order to optimize their postoperative course. Conclusion: Perioperative patient education, regardless of how it is implemented, constitutes both an integral part of the nursing care and an independent nursing intervention per se, which strengthens the nurses' autonomy and improves the patient's postoperative course.

    ABSTRACT Background: The chronic kidney disease is a major health concern. The number of the elderly people with chronic renal failure has increased across the world. Dialysis is an appropriate therapy for the elderly, but it involves certain challenges. The present paper reports uncertainty as part of the elderly experiences of living with hemodialysis. Methods: This qualitative study applied Max van Manen interpretative phenomenological analysis to explain and explore experiences of the elderly with hemodialysis. Given the study inclusion criteria, data were collected using in-depth unstructured interviews with nine elderly undergoing hemodialysis, and then analyzed according to Van Manen 6-stage methodological approach. Results: One of the most important findings emerging in the main study was “uncertainty”, which can be important and noteworthy, given other aspects of the elderly life (loneliness, despair, comorbidity of diseases, disability, and mental and psychosocial problems). Uncertainty about the future is the most psychological concerns of people undergoing hemodialysis. Conclusion: The results obtained are indicative of the importance of paying attention to a major aspect in the life of the elderly undergoing hemodialysis, uncertainty. A positive outlook can be created in the elderly through education and increased knowledge about the disease, treatment and complications. PMID:28097174

  6. Selected indices of peritoneal fibrosis in patients undergoing peritoneal dialysis

    Józef Penar

    2009-04-01

    Full Text Available Peritoneal dialysis is an alternative to hemodialysis in the treatment of patients with end-stage renal disease. Long-term use of peritoneal dialysis is limited by progressive alterations in the peritoneal membrane. The pathological changes in the peritoneum are due to the exposure to traditional nonphysiological peritoneal dialysis fluids that have low pH, high glucose and glucose degradation product content, and high molarity. Repeated episodes of bacterial peritonitis are another cause of peritoneal membrane damage. The characteristic features of peritoneal alterations include peritoneal fibrosis and morphologic changes in the peritoneal microvasculature with the accumulation of extracellular matrix in the submesothelial area and loss of mesothelial cells. These changes in the peritoneal membrane cause ultrafiltration failure and loss of dialysis efficacy. The pathogenesis of the peritoneal membrane damage is very complicated and understanding the processes involved in these alterations will be crucial in improving treatment with peritoneal dialysis. Some points of view on fibrosis of peritoneal membrane in patients undergoing peritoneal dialysis are presented here.

In spite of initial encouraging technical success after femoropopliteal percutaneous transluminal angioplasty or stenting, postprocedural restenosis remains the major problem. The challenging idea behind the drug-coated balloon (DCB concept is the biological modification of the injury response after balloon dilatation. Antiproliferative drugs administered via DCBs or drug-eluting stents are able to suppress neointimal hyperplasia, the main cause of restenosis. This article reviews the results of DCB treatments of femoropopliteal and infrapopliteal lesions in comparison to standard angioplasty with uncoated balloons. A systematic literature search was performed in 1 medical journals (ie, MEDLINE, 2 international registers for clinical studies (ie, www.clinicaltrials.gov, and 3 abstracts of scientific sessions. Several controlled randomized trials with follow-up periods of up to 5 years demonstrated the efficacy of paclitaxel –DCB technology. However, calcified lesions seem to affect the efficacy of DCB. Combinations of preconditioning methods with DCBs showed promising results. Although the mechanical abrasion of calcium via atherectomy or laser ablation showed favorable periprocedural results, the long-term impact on restenosis and clinical outcome has to be demonstrated. Major advantages of the DCBs are the rapid delivery of drug at uniform concentrations with a single dose, their efficacy in areas wherein stents have been

    Intestinal malrotation is a rare congenital anomaly. In adults is very difficult to recognize due to the lack of symptoms. Diagnosis is usually incidental during surgical procedures or at autopsy. To review the occurrence and recognition of uneventful intestinal malrotation discovered during regular cases of bariatric surgeries. Were retrospectively reviewed the medical registry of 20,000 cases undergoing bariatric surgery, from January 2002 to January 2016, looking for the occurrence of intestinal malrotation and consequences in the intraoperative technique and immediate evolution of the patients. Five cases (0,025%) of intestinal malrotation were found. All of them were males, aging 45, 49, 37,52 and 39 years; BMI 35, 42, 49, 47 and 52 kg/m2, all of them with a past medical history of morbid obesity. The patient with BMI 35 kg/m2 suffered from type 2 diabetes also. All procedures were completed by laparoscopic approach, with no conversions. In one patient was not possible to move the jejunum to the upper abdomen in order to establish the gastrojejunostomy and a sleeve gastrectomy was performed. In another patient was not possible to fully recognize the anatomy due to bowel adhesions and a single anastomosis gastric bypass was preferred. No leaks or bleeding were identified. There were no perioperative complications. All patients were discharged 72 h after the procedure and no immediate 30-day complications were reported. Patients with malrotation can successfully undergo laparoscopic bariatric surgery. May be necessary changes in the surgical original strategy regarding the malrotation. Surgeons must check full abdominal anatomical condition prior to start the division of the stomach.

    We present 2 patients with Moyamoya disease undergoing revascularization surgery who developed transient intraoperative central diabetes insipidus with spontaneous resolution in the immediate postoperative period. We speculate that patients with Moyamoya disease may be predisposed to a transient acute-on-chronic insult to the arginine vasopressin-producing portion of their hypothalamus mediated by anesthetic agents. We describe our management, discuss pertinent literature, and offer possible mechanisms of this transient insult. We hope to improve patient safety by raising awareness of this potentially catastrophic complication.

    Full Text Available Abstract Background Functional endoscopic sinus surgery (FESS is now a well-established strategy for the treatment of chronic rhinosinusitis which has not responded to medical treatment. There is a wide variation in the practice of FESS by various surgeons within the UK and in other countries. Objectives To identify anatomic factors that may predispose to persistent or recurrent disease in patients undergoing revision FESS. Methods Retrospective review of axial and coronal CT scans of patients undergoing revision FESS between January 2005 and November 2008 in a tertiary referral centre in South West of England. Results The CT scans of 63 patients undergoing revision FESS were reviewed. Among the patients studied, 15.9% had significant deviation of the nasal septum. Lateralised middle turbinates were present in 11.1% of the studied sides, and residual uncinate processes were identified in 57.1% of the studied sides. There were residual cells in the frontal recess in 96% of the studied sides. There were persistent other anterior and posterior ethmoidal cells in 92.1% and 96% of the studied sides respectively. Conclusions Analysis of CT scans of patients undergoing revision FESS shows persistent structures and non-dissected cells that may be responsible for persistence or recurrence of rhinosinusitis symptoms. Trials comparing the outcome of conservative FESS techniques with more radical sinus dissections are required.

    The study aimed to examine the association between incidentally discovered mesenteric artery stenosis, renal artery stenosis (RAS) and coronary artery disease in patients undergoing coronary angiography. We performed a prospective analysis of consecutive patients undergoing routine cardiac catheterisation. Abdominal aortograms in lateral and antero-posterior view were obtained to assess arterial stenosis of the coeliac axis, superior mesenteric artery and renal arteries. Significant arterial stenosis was defined as a narrowing of at least 50% compared with the normal artery. Demographic data and cardiovascular risk factors were analysed. The prevalence of visceral artery stenosis (VAS) was 63/450 (14%) including 48/450 (10.6%) cases of coeliac axis stenosis and 15/450 (3.3%) cases of superior mesenteric artery stenosis. Female sex (p = 0.01), older age (p = 0.03) and the presence of coronary artery disease (p = 0.05) were significant predictors for the presence of VAS in univariate analysis. The determinants for VAS in multivariate analysis were female sex and three-vessel coronary artery disease, while two- and three-vessel coronary artery disease was significant for RAS. Screening for VAS and RAS in female patients older than 60 years with more than two diseased coronary segments could have a high diagnostic value.

    In industrialized countries lung cancer is associated with highest mortality among carcinoma. Progression of the disease is associated with diminished tolerance for physical activities, aggravated dyspnea and lowering of life quality. The aim of study was the evaluation of blood gas, blood saturation and chosen parameters of spirometric examination in NSCLC patients undergoing chemotherapy and pulmonary rehabilitation. Analysis of capillary blood was done using RapidPoint 405 Siemens device. Spirometric examination was done using PNEUMO abcMED device. Forty-nine patients with inoperable NSCLC were subjected to the examination. This included 38 men and 11 women aged between 46-75 years (mean age 63 +/- 7.5 years) who were separated into two groups: group I--25 patients undergoing standard chemotherapy (group C); group II--24 patients undergoing standard chemotherapy and pulmonary rehabilitation (group CK). All patients were subjected to blood gas analysis, blood saturation analysis and spirometric examination twice, before and after first-line chemotherapy Increase of pO2 and SaO2 in blood, and FEV1 and FVC in spirometric examination was significantly higher in patients undergoing pulmonary rehabilitation and chemotherapy (group II) (p < 0.05) in comparison to NSCLC patients undergoing only chemotherapy (group I). Pulmonary rehabilitation of NSCLC patients undergoing first-line chemotherapy results in improvement of indicators of blood gas, blood saturation analysis and chosen parameters of spirometric analysis. Pulmonary rehabilitation in patients with lung cancer seems to be an important form of supplementary treatment.

    Endovascular intervention has become a well-recognized treatment modality for peripheral artery disease; however, mid- and long-term outcomes have been plagued by limited durability. Plain balloon angioplasty and bare-metal stents have historically suffered from high restenosis rates leading to the need for frequent repeat revascularization procedures. The innovation of locally administered, drug-delivering balloons and stents has been a direct result of technological innovations directed toward prevention and treatment of this limitation. Over the last 5 years, numerous clinical trials investigating the use of drug-coated stents and drug-coated balloons indicate a significant improvement in endovascular treatment durability and outcomes. This review provides an up-to-date assessment of the current evidence for the use of drug-coated stents and drug-coated balloons in the treatment of femoropopliteal and infrapopliteal peripheral artery disease. Additionally, it provides an overview of the development of this technology, highlights landmark ongoing and completed clinical trials, examines evidence to support the use of drug-coated technologies in combination with other modalities, and examines promising new technological developments. Last, it summarizes the challenges and safety concerns that have delayed U.S. Food and Drug Administration approval of these devices.

    Background Only a small proportion of patients referred for coronary angiography with suspected coronary artery disease (CAD) have the diagnosis of obstructive CAD confirmed by the exam. For this reason, further strategies for risk stratification are necessary. Objective To investigate the relationship of the presence of fragmented QRS (fQRS) on admission electrocardiogram with angiographically detected CAD and CAD severity in patients without known vascular diseases and myocardial fibrosis, undergoing first diagnostic coronary angiography. Methods We enrolled 336 consecutive patients undergoing coronary angiography for suspected CAD. The patients were divided into two groups according to the presence or absence of fQRS on admission. We compared the groups regarding the presence and severity of CAD. Results Seventy-nine (23.5%) patients had fQRS on admission. There was not a statistically significant difference between patients with fQRS (41.8%) and non-fQRS (30.4%), regarding the presence of CAD (p = 0.059). However, there was a statistically significant difference between patients with fQRS and non-fQRS regarding the presence of stenotic CAD (40.5% vs. 10.5%, p22 compared to patients with SYNTAX score ≤22. Conclusions Our findings suggest that fQRS may be an indicator of early-stage myocardial damage preceding the appearance of fibrosis and scar, and may be used for risk stratification in patients undergoing first diagnostic coronary angiography PMID:27849256

    Purpose: direct intra-arterial thrombolysis is the standard of care over acute surgical intervention for acute infrainguinal occlusion. However, several mechanical thrombectomy devices can be utilized as a less invasive alternative to rapid reperfusion of the acutely threatened limb. Materials end methods: retrospective analysis of 265 patients treated from 1999 to 2005, mean age 65 {+-} 8.4 (range from 47 to 75) years, with acute (85 patients, 32.1%, group 1) or subacute (180 patients, 67.9%, group 2) occlusions of the femoropopliteal artery with a rotational thromboembolectomy system (Straub Rotarex registered). The mean occlusion length was 25 (range 2 - 40) cm. Results: the technical success rate was 94.7% (251 / 265). In the additional 14 patients, no complete clot removal (n = 9) or intraluminal guidewire passage was able to be achieved (n = 5). After a mean follow-up of 12 {+-} 3 months, the restenosis rate was 49% in group 1 and 54% in group 2. The ankle-brachial index improved in group 1 from 0.32 {+-} 0.17 to 0.78 {+-} 0.24 at discharge and 0.71 {+-} 0.23 after 12 months (p {<=} 0.001) and in group 2 from preinterventional 0.47 {+-} 0.24 to 0.81 {+-} 0.19 at discharge and 0.74 {+-} 0.24 after 12 months (p {<=} 0.001). There were 16 (6%) distal embolizations and 3 (1.2%) perforations. There were no cases of amputation or death during follow-up. (orig.)

We sought to investigate whether OSA affects the clinical outcomes of patients undergoing PCI.Patients and methods: All enrolled individuals treated with PCI were evaluated for OSA by polysomnography. The primary end point was defined as major adverse cardiac events (MACEs at 2 years, including cardiac death, myocardial infarction (MI, and/or target vessel revascularization.Results: A total of 340 consecutive patients undergoing PCI were assigned to the OSA (n=152, apnea–hypopnea index ≥15 and non-OSA (n=188, apnea–hypopnea index <15 groups. The incidence of OSA in patients with coronary artery disease undergoing PCI was 44.7%. Patients in the OSA group had more three-vessel disease (34.9%, increased number of total implanted stents (3.3±2.0, and longer total stent length (83.8±53.1 mm when compared to the non-OSA group (23.4%, P=0.020; 2.8±1.9, P=0.007; 68.7±48.4, P=0.010. After a median follow-up of 2 years, the incidence of MACEs was significantly higher in patients with OSA (25.0% vs 16.0%, P=0.038, mainly driven by the increased periprocedural MI (19.2% vs 11.2%, P=0.038 in the OSA group. By Cox regression multivariable analysis, the independent predictor of MACEs was OSA (hazard ratio: 1.962, 95% confidence interval: 1.036–3.717, P=0.039.Conclusion: There was a high prevalence of moderate-to-severe OSA

    A major decline in pulmonary function is observed on the first day after upper abdominal surgery. This decline can reduce vital and inspiratory capacity and can culminate in restrictive lung diseases that cause atelectasis, reduced diaphragm movement, and respiratory insufficiency. The objective of this study was to evaluate the efficacy of preoperative ambulatory respiratory muscle training in patients undergoing esophagectomy. The sample consisted of 20 adult patients (14 men [70%] and 6 women [30%]) with a diagnosis of advanced chagasic megaesophagus. A significant increase in maximum inspiratory pressure was observed after inspiratory muscle training when compared with baseline values (from -55.059 ± 18.359 to -76.286 ± 16.786). Preoperative ambulatory inspiratory muscle training was effective in increasing respiratory muscle strength in patients undergoing esophagectomy and contributed to the prevention of postoperative complications.

    Full Text Available Background: Juvenile myasthenia gravis (JMG is the rare form of myasthenia gravis presenting in childhood and adolescence. When medical management fails, thymectomy is offered for these patients. Complete resection of the thymus is best achieved through transsternal thymectomy. Anesthetic management of patients with JMG is challenging, particularly in regards to the goals of postoperative pain control, respiratory function, and extubation. Methods: We retrospectively reviewed the medical records of 13 patients, ranging in age from 6 to 22 years, who underwent transsternal thymectomy for JMG. Information on patient demographics, characteristics of their disease and treatment, anesthetic management, and postoperative course were collected. Results: All patients had undergone multiple treatment modalities and presented for surgery because of inadequate symptom control with medical management. As expected for a pediatric population, anesthesia induction was age dependent. 40% of the patients underwent an inhalation induction and 60% underwent an intravenous induction. Anesthesia was maintained with a low-dose inhalation agent in all patients, supplemented in 84% of patients with a remifentanil infusion, and in 69% of patients with an epidural infusion. Muscle relaxants were avoided in all patients. With this regimen, 92% of patients could be extubated successfully in the operating room. Conclusion: We found that avoidance of muscle relaxants and use of remifentanil with a low-dose hypnotic agent provided a stable intraoperative course, facilitated rapid emergence, and allowed early extubation in patients with JMG undergoing transsternal thymectomy. Epidural analgesia reduced the need for intra- and postoperative intravenous opioids and did not have an adverse effect on respiratory strength.

    To investigate a recent association between the use of the angiotensin receptor-blocker (ARB) olmesartan and a severe enteropathy resembling celiac disease. We searched our endoscopy database for all outpatient esophagogastroduodenoscopy (EGD) or colonoscopy examinations in patients aged at least 50 years during the period January 1, 2007, to March 31, 2013. Cases were those whose examination indication was diarrhea, and controls were those whose examination indication was esophageal reflux (EGD) or colorectal cancer screening (colonoscopy). We compared cases with controls with regard to the proportion of those listing olmesartan among their medications. Secondary exposures were the proportion of those taking nonolmesartan ARBs or other antihypertensive medications. We also examined biopsy results to determine whether there were histologic changes associated with the use of olmesartan. We identified 2088 patients undergoing EGD and 12,428 patients undergoing colonoscopy meeting inclusion criteria. On multivariate analysis, there was no statistically significant association between olmesartan and diarrhea among those undergoing EGD (odds ratio, 1.99; 95% CI, 0.79-5.00) or colonoscopy (odds ratio, 0.63; 95% CI, 0.23-1.74). Review of pathology reports of the EGD and colonoscopy groups showed no association between the use of olmesartan and the histologic diagnosis of celiac disease (P=.61) or microscopic colitis (P=1.0), respectively. Our findings suggest that neither olmesartan nor other ARBs were associated with diarrhea among patients undergoing endoscopy. The spruelike enteropathy recently associated with olmesartan is likely a rare adverse effect and milder presentations are unlikely.

    Purpose: To investigate the incidence and clinical significance of platelet responsiveness in patients receiving clopidogrel after peripheral angioplasty procedures. Materials and Methods: This prospective study included patients receiving antiplatelet therapy with clopidogrel 75 mg after infrainguinal angioplasty or stenting and who presented to our department during routine follow-up. Clopidogrel responsiveness was tested using the VerifyNow P2Y12 Assay. Patients with residual platelet reactivity units (PRU) {>=} 235 were considered as nonresponders (NR group NR), whereas patients with PRU < 235 were considered as normal (responders [group R]). Primary end points were incidence of resistance to clopidogrel and target limb reintervention (TLR)-free survival, whereas secondary end points included limb salvage rates and the identification of any independent predictors influencing clinical outcomes. Results: In total, 113 consecutive patients (mean age 69 {+-} 8 years) with 139 limbs were enrolled. After clopidogrel responsiveness analysis, 61 patients (53.9 %) with 73 limbs (52.5 %) were assigned to group R and 52 patients (46.1 %) with 66 limbs (47.5 %) to group NR. Mean follow-up interval was 27.7 {+-} 22.9 months (range 3-95). Diabetes mellitus, critical limb ischemia, and renal disease were associated with clopidogrel resistance (Fisher's exact test; p < 0.05). According to Kaplan-Meier analysis, TLR-free survival was significantly superior in group R compared with group NR (20.7 vs. 1.9 %, respectively, at 7-year follow-up; p = 0.001), whereas resistance to clopidogrel was identified as the only independent predictor of decreased TLR-free survival (hazard rate 0.536, 95 % confidence interval 0.31-0.90; p = 0.01). Cumulative TLR rate was significantly increased in group NR compared with group R (71.2 % [52 of 73] vs. 31.8 % [21 of 66], respectively; p < 0.001). Limb salvage was similar in both groups. Conclusion: Clopidogrel resistance was related with

    Objective To explore the relationship of inflammatory response of the respiratory tract and prognosis of chronic obstructive pulmonary diseases (COPD) patients undergoing mechanical ventilation (MV) in respiratory intensive care unit (RICU). Methods Thirty patients with COPD undergoing MV were involved in the study, and divided into survival group (n=16) and non-survival group (n=14). Exhaled breath condensate (EBC) was collected on day 1,3,5,7 after MV. The concentration of hydrogen peroxide (H2O2) in EBC was measured fluorimetrically. The content of interleukin-6(IL-6) in EBC was measured by enzyme-linked immunosorbent assay (ELISA). Results ①The significantly lower H2O2 and IL-6 levels in the survival group were observed on days 3,5 and 7 compared with those of day 1 after MV [H2O2 (μmol/L): 0.10±0.03, 0.06±0.03, 0.04±0.03 vs.0.19±0.14,IL-6 (ng/L):11.11±2.39,10.35±2.09,8.89±2.63vs. 14.45±6.03,all P0.05). A significantly higher H2O2 level in non-survivors was observed compared with survivors on day 5 (P0.05). Conclusion The findings suggest that the levels of H2O2 and IL-6 in EBC are correlated with prognosis of patients undergoing MV, and it may prove to be useful in monitoring inflammatory response in the airway after MV as a guidance of therapy and prognosis in COPD patients undergoing MV.%目的 探讨呼吸重症监护病房(RICU)慢性阻塞性肺疾病(COPD)机械通气患者气道炎症反应与预后的关系.方法 30例COPD机械通气患者按预后分为存活组(16例)和死亡组(14例),采用自行设计的呼出气冷凝液(EBC)收集器收集机械通气1、3、5和7 d呼气端的EBC,用化学荧光法测定EBC中过氧化氢(H2O2)浓度,用酶联免疫吸附法测定EBC中白细胞介素-6(IL-6)含量.结果 ①存活组EBC中H2O2和IL-6含量逐渐下降,机械通气3、5、7 d较1 d明显降低[H2O2(μmol/L):0.10±0.03、0.06±0.03、0.04±0.03比0.19±0.14,IL-6(ng/L):11.11±2.39、10.35±2.09、8.89±2.63比14.45±6.03,均P0

We sought to document the prevalence and identify the predictors of unwillingness to undergo surgery among a cohort of hip/knee, foot/ankle, neck/back, and hip/knee patients.Patients and methods: Patient demographics and information on patient health status, perceptions of risk and success of surgery, and willingness to undergo surgery were collected. Sequential logistic regression models were used to investigate the influence of the captured variables on willingness to undergo surgery.Results: Overall, 392 (20% of 1946 participants reported being unwilling to undergo or unsure about undergoing (“unwilling/unsure” surgery if it was offered to them. From adjusted analyses, low income and non-White ethnicity were associated with a greater likelihood of being unwilling/unsure. Compared with hip/knee patients, neck/back patients were more likely to report being unwilling/unsure (odds ratio: 1.90 [95% confidence interval: 1.36, 265]; no differences were found between the remaining anatomical groups. However, when perceptions of risk and success were additionally considered, the influence for the neck/back cohort was significantly attenuated. Foot/ankle and elbow/shoulder patients were found to be significantly less likely to report unwillingness when perceptions were considered.Conclusion: In addition to demographic/economic influences, perceptions of surgical risk and success play a critical role in patients’ willingness to undergo surgery.Keywords: risk perception, orthopedic surgery

    This study was designed to evaluate the role of music therapy on the level of stress in children undergoing repair of congenital heart disease. Prospective, randomized, double-blind, controlled clinical trial. Children's university hospital. Fifty children aged 4 to 12 years undergoing repair of congenital heart disease. Patients were randomized into 2 equal groups (control group and music group); in the control group, patients listened to a blank CD, and in the music group, patients listened to a recorded CD of music and songs preferred by the child. Demographic data, clinical data, and preoperative vital signs were recorded. Baseline stress markers (blood glucose and cortisol levels) were sampled. Patients were assessed intraoperatively until extubation for vital signs and stress markers and after extubation for pain and sedation scales. An interview was conducted within the first postoperative week with the patients and their parents for assessment of post-traumatic stress disorder and negative postoperative behavior changes. There were no significant differences in demographic characteristics, clinical data, vital signs, preoperative and at-extubation blood glucose levels, and preoperative blood cortisol levels between groups. Significant differences were found between groups in blood glucose levels and cortisol levels at all intraoperative times, but only in cortisol blood levels at extubation. Significant differences were found in pain score, sedation score, occurrence of child post-traumatic stress disorder, and occurrence of negative postoperative behavior. Listening to favorable music by children undergoing repair for congenital heart disease resulted in less stress and more relaxation. Copyright © 2015 Elsevier Inc. All rights reserved.

    This study was carried out on wholebody radiation dose assessment to paediatrics patient who undergo PET/CT scanner at Institut Kanser Negara. Consist of 68 patients with varies of malignancies and epilepsy disease case covering age between 2 years to 12 years old. This is a retrospective study from 2010-2014. The use of PET/CT scanner as an advanced tool has been proven to give an extra radiation dose to the patient. It is because of the radiation exposure from the combination of both CT and PET scans rather than a single CT or PET scan. Furthermore, a study on radiation dose to paediatric patient undergoing PET/CT is rare in Malaysia. So, the aim of this study is to estimate the wholebody effective dose to paediatric patient in Malaysia. Effective dose from PET scan was calculated based on the activity of F18 FDG and dose coefficient reported in International Commission on Radiological Protection (ICRP) Publication 106. Effective dose from CT was determined using k coefficient as reported in ICRP publication 102 and Dose Length Product (DLP) value. The average effective dose from PET and CT were found to be 7.05mSv and 5.77mSv respectively. The mean wholebody effective dose received by a patient with combined PETCT examination was 12.78mSv. These results could be used as reference for dosimetry of a patient undergoing PETCT examination in Malaysia.

    The aim of this study is to compare the hemodynamic effects of neostigmine-atropine combination and sugammadex in patients with cardiac problems undergoing noncardiac surgery. Prospective randomized study. In the operating room. Ninety patients with a class 2 or 3 cardiovascular disease according to the New York Heart Association classification and aged between 18 and 75 years undergoing noncardiac surgery were randomized. Group N (n = 45) received 0.03 mg/kg IV neostigmine when T2 appeared as measured with a nerve muscle stimulator. When heart rate was 5 beats/min (±10 beats/min) lower than the heart rate before administration of the medication, 0.5 mg IV atropine sulfate was given. Group S (n = 45) received 3 mg/kg IV sugammadex when T2 appeared as measured with a nerve muscle stimulator. Heart rate, mean systolic and diastolic blood pressures, and electrocardiographic alterations including the QTc (QT Fredericia and QT Bazett) were recorded. There were no significant differences between and within the groups in terms of QTc values. Sugammadex group had a significant decrease on heart rate 1 minute after the medication when compared to the measurement before the medication (P Sugammadex group had lower systolic, diastolic, and mean blood pressures and heart rate when compared to neostigmine group (P sugammadex might be preferred as it provides more hemodynamic stability compared to neostigmine-atropine combination to reverse rocuronium-induced neuromuscular blockage in cardiac patients undergoing noncardiac surgery.

    Guillotine amputation for diabetic foot sepsis followed by an elective refashioning of the stump is regarded as standard practice. Primary amputation is associated with higher reamputation rates. A prospective cohort study of 85 patients who underwent surgery for diabetic foot sepsis from 2014 to 2016 at Madadeni Provincial Hospital, KwaZulu-Natal was done. Ethical approval was granted. The Wagner classification (Wag) was used to classify disease severity. Outcome measures included length of hospital stay, mortality and re-amputation rates. Of the 85 patients, females (n=45) accounted for 53% of admissions. The mean age was 61 years (range: 29 to 80 years). The majority of patients were African, n=75 (88%). Only 1 patient presented with diabetic ketoacidosis and 18 (21%) presented with renal failure. Most patients presented with advanced disease: [Wag 5, n=66 (78%); Wag 4, n=12 (14%); Wag 3, n=5 (6%); Wag 2, n=2 (2%)]. The levels of vascular occlusion included aortoiliac disease n=2 (2%), femoro-popliteal disease n=18 (21%), tibio-peroneal disease n=65 (76%). Radiographic features included normal findings n=60 (71%); gas gangrene n=11 (13%), osteitis n=8 (9%). The following amputations were done: AKA, n=29 (34%); BKA, n=39 (46%); TMA, n=8 (9%); Toe-ectomy, n=5 (6%) and Debridement, n=4 (5%). The re-amputation rate to above knee amputation was n= 3/39 (8%). All AKA stumps healed well. The overall in-hospital mortality was n=5 (6%) and mean length of hospital stay was 7.8 days ±3.83. The majority of patients presented with advanced disease requiring a major amputation. A definitive one stage primary amputation is a safe and effective procedure for diabetic foot sepsis and is associated with a low re-amputation rate, length of hospital stay and mortality. A guillotine amputation should be reserved for physiologically unstable patients.

    Full Text Available Indian patients undergoing cardiac surgery have different demographics, clinical profile as well as risk profile, compared to the western population. The purpose of this study was to validate the European System for Cardiac Operative Risk Evaluation (EuroSCORE risk stratification model in Indian patients undergoing cardiac surgery in a single cardiac center. Data from 1000 consecutive adult patients undergoing cardiac surgery (coronary artery bypass grafting or valve surgery were prospectively collected as per the EuroSCORE model. The model′s validity was assessed on the basis of its calibration power (Hosmer-Lemeshow test and discriminatory power [area under receiver operating characteristic curve]. The patients were divided into three risk groups on the basis of their EuroSCORE. The Hosmer-Lemeshow test revealed a good calibration power (P = 0.73 and the area under the ROC curve was 0.8278, suggesting a good discriminative power. The predicted mortality was similar to observed mortality in low- and moderate-risk patients but the observed mortality in high-risk patients (15.6% was double that of predicted mortality (7.5%. The risk factors prevalent in European population were not observed in Indian population. EuroSCORE accurately predicts mortality in low and moderate-risk Indian patients undergoing cardiac surgery but is less predictive for high-risk Indian patients. Updating and improvisation of EuroSCORE by incorporation of risk factors associated with rheumatic valvular heart disease which is more prevalent in India, may enable it to accurately predict mortality in high-risk patients also.

    A sample of 204 British participants completed a questionnaire that assessed their attitude toward cosmetic surgery as well as measures of self-esteem, life satisfaction, self-rated physical attractiveness, religiosity and media consumption. Two factors emerged from a factor analysis of their attitudes toward surgery: likelihood to undergo, and benefits of undergoing, cosmetic surgery. Females with low self-esteem, low life satisfaction, low self-rated attractiveness and little religious beliefs who were heavy television watchers reported a greater likelihood of undergoing cosmetic surgery. Stepwise regression analysis with the two attitude factors as criterion variables showed two major predictors for likelihood: religiousness and low self-esteem, and four major predictors for benefit: religousness, media consumption, life satisfaction and sex. The role of religion is considered in this context.

    Malnutrition has been linked to serious complications in patients undergoing elective total joint arthroplasty (TJA). This study prospectively evaluated 2,161 patients undergoing elective TJA for malnutrition as defined by either an abnormal serum albumin or transferrin. The overall incidence of malnutrition was 8.5% (184 of 2,161) and the rate of overall complications in the malnourished group was 12% as compared to 2.9% in patients with normal parameters (PMalnutrition predicted serious complications involving hematoma formation, infection, renal and cardiac complications. Obesity, defined by a body mass index (BMI) of 30kg/m(2) was present in 42.9% of malnourished patients with a significantly higher complication rate in this cohort. Malnutrition remains prevalent in patients >55years-old undergoing TJA and is associated with a significant increase in post-operative complications.

    The Prevention of Orthopaedic Implant Infection in Patients Undergoing Dental Procedures evidence-based clinical practice guideline was codeveloped by the American Academy of Orthopaedic Surgeons (AAOS) and the American Dental Association. This guideline replaces the previous AAOS Information Statement, "Antibiotic Prophylaxis in Bacteremia in Patients With Joint Replacement," published in 2009. Based on the best current evidence and a systematic review of published studies, three recommendations have been created to guide clinical practice in the prevention of orthopaedic implant infections in patients undergoing dental procedures. The first recommendation is graded as Limited; this recommendation proposes that the practitioner consider changing the long-standing practice of routinely prescribing prophylactic antibiotic for patients with orthopaedic implants who undergo dental procedures. The second, graded as Inconclusive, addresses the use of oral topical antimicrobials in the prevention of periprosthetic joint infections. The third recommendation, a Consensus statement, addresses the maintenance of good oral hygiene.

    Summary Introduction: The merging of medicine with information technology facilitates the retrieval of stored data, aiding the conduct of research with greater scientific rigor. Studies in the field of otorhinolaryngology, specifically in the area of laryngology and voice, are of fundamental importance, since 70% of the economically active need their voice to work. Objective: To create a computerized protocol of the diseases of the larynx, apply and validate it, and use it to evaluate patients undergoing laryngoscopic microsurgery of the larynx. Method: We created a database of ENT diseases through a literature review of textbooks and scientific articles. Next, we computerized the data and incorporated it into the SINPE©, creating a master protocol (ENT diseases) and a specific protocol (laryngeal diseases). Data were collected prospectively from patients undergoing laryngeal microsurgery in the ENT Hospital of Paraná. The collected data were analyzed with graphs through the SINPE© Analyzer module. Results: We evaluated 245 patients aged 9–79 years, and determined that 36.61% (93 patients) underwent surgery for the presence of polyps on the vocal folds, 12.6% (32) underwent surgery for papillomatosis, and 11.83% (29) underwent surgery for intracordal cysts. Conclusions: The creation of an electronic database of clinical ENT diseases was feasible. We were also able to implement and validate the protocol. The database may be released to physicians involved in clinical data collection and retrieval of information to conduct scientific research in an organized manner. The most common laryngeal disorders identified were polyps, papilloma, and intracordal cysts. PMID:25991956

Objective: To create a computerized protocol of the diseases of the larynx, apply and validate it, and use it to evaluate patients undergoing laryngoscopic microsurgery of the larynx. Method: We created a database of ENT diseases through a literature review of textbooks and scientific articles. Next, we computerized the data and incorporated it into the SINPE©, creating a master protocol (ENT diseases and a specific protocol (laryngeal diseases. Data were collected prospectively from patients undergoing laryngeal microsurgery in the ENT Hospital of Paraná. The collected data were analyzed with graphs through the SINPE© Analyzer module. Results: We evaluated 245 patients aged 9-79 years, and determined that 36.61% (93 patients underwent surgery for the presence of polyps on the vocal folds, 12.6% (32 underwent surgery for papillomatosis, and 11.83% (29 underwent surgery for intracordal cysts. Conclusions: The creation of an electronic database of clinical ENT diseases was feasible. We were also able to implement and validate the protocol. The database may be released to physicians involved in clinical data collection and retrieval of information to conduct scientific research in an organized manner. The most common laryngeal disorders identified were polyps, papilloma, and intracordal cysts.

    While laparoscopic colorectal resection may be underused in technically challenging circumstances, the minimally invasive approach may in fact maximally benefit patients at the greatest risk of complications. Obesity and proctectomy pose particular technical challenges during laparoscopic resection and are also associated with the greatest risks of complications, especially surgical site infections (SSIs). We evaluated the role of laparoscopy in minimizing SSI in such patients. From the American College of Surgeons-National Surgical Quality Improvement Program database, outcomes for obese [body mass index (BMI) ≥ 30 kg/m(2)] and non-obese (BMI laparoscopy on SSI for obese patients undergoing proctectomy. OC patients were more likely than OP, LC, and LP, respectively, to undergo emergency operation and have an American Society of Anesthesiologists (ASA) score of 3-5. Overall SSI rates after OC, OP, LC, and LP were 15.2, 17.6, 8.6, and 10.1 %, respectively (p obese patients, the rates were 18.7, 22.3, 10.7, and 13.3 % (p obesity, proctectomy, younger age, race, steroid use, diabetes, chronic obstructive pulmonary disease, prior wound infection, transfusion history, previous operation within 30 days, coronary artery or vascular disease, ASA class 3-5, tobacco use, resident involvement, male gender, albumin Laparoscopy reduced the risk of SSI by at least 35 % across all BMI classes and procedures, an effect that persisted on multivariate analysis even in obese patients undergoing proctectomy. In colorectal surgery, an already high-risk outlier for SSI, obesity and proctectomy are associated with the highest risk of SSI. Despite the particular technical challenges of laparoscopy in these circumstances, the minimally invasive approach attenuates the risk of SSI in these high-risk patients and thus should be strongly considered during treatment planning.

    It has become widely accepted that whenever animals are used in scientific procedures, the 3Rs principle of replacement, reduction and refinement described by William Russell and Rex Burch should be adhered to. Animals should be replaced with non-sentient alternatives if possible, the number of animals used should be reduced and experimental procedures should be refined to minimise pain, suffering and distress. Administration of analgesic agents to animals undergoing surgical procedures is a refinement used to alleviate pain. In this study, a structured literature review was carried out to examine current trends in analgesic administration to rabbits undergoing experimental surgical procedures. 128 papers from 51 peer-reviewed journals were selected for inclusion in this review.

    Chromosomal abnormalities are the major contributor to the genetic risks of infertility treatment associated with intracytoplasmic sperm injection (ICSI). The study objective was to assess prospectively the frequency of chromosomal aberrations in couples undergoing ICSI. A total of 2650 infertile couples (5300 patients) underwent chromosome analysis before undergoing ICSI in the Egyptian IVF-ET Centre. Heparinized blood samples were cultured, harvested and banded according to standard methods. Overall, 96.94% of the patients studied (5138/5300) had a normal karyotype, while the remaining 162 patients (3.06%) had an abnormal karyotype. Male patients constituted the majority of abnormalities; 138 males (85.19%) and 24 females (14.81%). These chromosomal aberrations included 117 cases (2.2%) of sex chromosome abnormalities; 113 males and four females. Forty-five patients (0.85%) had autosomal aberrations; 25 of them were males and 20 were females. The current data show that chromosomal abnormalities affect 3.06% of infertile patients, and occur in both sexes, but more predominantly in males undergoing ICSI for male factor infertility. It is recommended that chromosomal analysis be performed before undergoing ICSI, to identify patients who can be offered preimplantation genetic diagnosis.

    We used {sup 18}F-FDG PET to evaluate the FDG uptake in patients with aggressive fibromatosis (AF, also known as desmoid tumours) undergoing therapy with imatinib (imatinib mesylate, Glivec). The pilot study included nine patients with progressive AF receiving oral treatment with imatinib at a daily dose of 800 mg. Patients were examined using PET prior to the start of therapy and during imatinib treatment. Restaging according to the Response Evaluation Criteria in Solid Tumors (RECIST) was performed in parallel using CT and/or MRI and served as reference. The clinical outcomes in nine evaluable patients were as follows: seven patients with stable disease, and two patients with progressive disease. A 27% decrease in the median average standardized uptake value (SUV) of the sequential PET examinations was demonstrated in all evaluable patients with three patients (33%) showing a decrease in SUV of more than 40% (48%, 52% and 54%, respectively); no patient showed a substantial increase in SUV. To our knowledge, this is the first series of AF patients undergoing treatment with imatinib and monitored using sequential PET imaging, that allows detection of SUV changes after imatinib induction, thus helping to decide whether treatment should be continued or not.

    As of 2000, more adults than children are alive with congenital heart disease. Each year, more of these adults with congenital heart disease undergo surgery. Adults with congenital heart disease require lifelong surveillance, follow-up imaging, and clinical decision making by appropriately trained and familiar physicians and extenders. Three common challenges facing adults with congenital heart disease are the neglected patient, weak programmatic infrastructure, and the planning and management of pregnancy in the adult with congenital heart disease. Many challenges must be overcome in order to establish and maintain a comprehensive medical and surgical program for adults with congenital heart disease. Three common and challenging groups of adults with congenital heart disease who may require surgery are adults requiring tricuspid valve surgery for Ebstein's malformation, those requiring reoperation for failing Fontan circulation, and those requiring pulmonary valve replacement (PVR). Surgery for Ebstein's anomaly is now offered to older patients at low risk and with good late outcome. The operation includes tricuspid valve repair or replacement and frequent concomitant procedures such as atrial septal defect closure, arrhythmia surgery (the Maze procedure), and coronary artery bypass grafting. Patients undergoing previous iterations of the Fontan operation are especially prone to arrhythmia and failing circulation. Fontan conversion with arrhythmia surgery and pacemaker therapy was developed by Constantine Mavroudis, Barbara Deal, and Carl Backer to treat these challenging patients, with the first such operation performed in 1994. Fontan conversion involves: (1) conversion of the previously created atriopulmonary connection to a total cavopulmonary connection (TCPC), extracardiac Fontan; (2) arrhythmia surgery, typically with a modified biatrial Maze procedure along with placement of an antitachycardia, dual-chamber pacemaker with steroid-eluting epicardial leads

    Full Text Available noBackground & Objectives: The postoperative Low T3 syndrome has been considered as a possible source of reduced myocardial contractility, resulting in increased mortality after CABG. Effect of preoperative Low T3 has not been well studied in patients undergoing CABG surgery. Aim of our study is to evaluate effect of preoperative Low T3 syndrome in patients undergoing CABG surgery.Materials & Methods: Six hundred and six patients undergoing CABG were included in this prospective study. The impact of the base-line FT3 concentration and of preoperative low T3 syndrome on the risk of postoperative low cardiac output and hospital death was analyzed.Results: Fifteen patients (2.3% postoperatively and 159 (26.2% developed major complications. At univariate analysis a reduced EF, the presence of peripheral vascular disease, the NYHA class, the surgical urgency, the aortic cross-clamp time, the CPB time and the FT3 concentration at admission were significantly associated with low CO and higher mortality. At multivariate analysis, the CPB time, an emergency procedure, a reduced LVEF, and the fT3 concentration were independently related to the development of low CO. However, in multivariate analysis low EF, and the fT3 concentration were the only predictors of hospital death.Conclusion: We conclude that preoperative low EF and low T3 syndrome independently causes low cardiac output and higher mortality in patients undergoing CABG. Therefore, all patients undergoing CABG should be evaluated for low T3 syndrome and patients with low T3 syndrome should be considered at increased risk. Appropriate preoperative T3 replacement therapy could decrease the postoperative complications in patients undergoing CABG.JCMS Nepal. 2015; 11(2:1-7

    Percutaneous balloon angioplasty is an endovascular technique for restoring blood flow through an artery that has become narrowed or blocked by atherosclerosis. Narrowing of the artery following angioplasty (restenosis) is the major cause of long-term failure. Cryoplasty offers a different approach to improving long-term angioplasty results. It combines the dilation force of balloon angioplasty with cooling of the vessel wall. This systematic review evaluated cryoplasty in peripheral arterial disease and provides focus for further research in the field. This is an update of a review first published in 2007. To assess the efficacy of, and complications associated with, cryoplasty for maintaining patency in the iliac, femoropopliteal and crural arteries in the short and medium term. For this update the Cochrane Peripheral Vascular Diseases Group Trials Search Co-ordinator searched the Specialised Register (last searched October 2012) and CENTRAL (2012, Issue 10). Trial databases were searched for ongoing or unpublished studies. We also searched the reference lists of relevant articles. All randomised controlled trials in which participants with peripheral arterial disease (PAD) of the lower limbs, or lower limb bypass graft stenoses, were randomised to cryoplasty with or without another procedure versus a procedure without cryoplasty were considered. This included trials where all participants received angioplasty and the randomisation was for cryoplasty versus no cryoplasty and trials where cryoplasty was used as an adjunct to conventional treatment (for example stenting) against a control. Two review authors independently reviewed, assessed and selected trials, extracted data and assessed risk of bias. Seven trials (six primary cryoplasty and one adjunctive cryoplasty trial) with a combined total of 478 patients were included in this review. The trials reported patency and restenosis either by participant, lesion or vessel location. Follow-up ranged from 30 days to

    Full Text Available CONTEXT Peripheral arterial disease of the lower extremity is an important cause of morbidity and affects 10 million people in India. AIMS AND OBJECTIVES The aims of this study were to assess the colour Doppler ultrasonography findings of lower limbs in patients with peripheral arterial disease by studying the spectral flow pattern and peak systolic velocity and also to assess the severity of stenosis and correlation of severity of stenosis on USG Doppler and MDCT angiography. MATERIALS AND METHODS The study included 29 patients attending surgery, Ortho OPD Government Medical College of Calicut with signs and symptoms of peripheral arterial diseases of lower limbs from January 2014 to October 2015 who underwent colour Doppler ultrasonography and MDCT angiography to know the severity of peripheral arterial diseases of lower extremities and to compare various grades of stenosis by studying the spectral flow patterns in colour Doppler ultrasonography and contrast opacification and diameter reduction in MDCT angiography. RESULTS In our study, 29 patients with intermittent claudication, numbness, and pain in the legs were selected. Majority of the patients were males and below 50 yrs. In our study, detection of totally occluded segments were better in MDCT angiography on comparing with Doppler USG. Most of the arteries showed good total agreement between Doppler and MDCT angiography. Aortoiliac group of vessels showed more than 80% total agreement between Doppler and MDCT angiography. Femoropopliteal group vessels showed more than 75% total agreement. Infrapopliteal group of vessels showed more than 50% total agreement. CONCLUSION MDCT angiography is more sensitive in detecting lesions of suprapopliteal group of vessels and also lesions with total occlusion of the lumen in comparison to Doppler ultrasonography. Imaging plays an important role in the management of the patients with peripheral arterial disease. Due to the limitations of the Doppler

    Defibrotide pharmacokinetics were studied in 6 voluntary healthy subjects and in 10 uremic patients undergoing dialysis during which (instead of heparin) defibrotide was administered to prevent fibrino-formation in the circuit. Blood concentrations of the drug were assessed (expressed with reference to the residual glycidic deoxyribose) during a standard dialysis using defibrotide, 3.5, 15, 30, 45, 60 and 90 minutes after the defibrotide bolus (200 mg) had been injected into the arterial channel. The half-lives of the alpha and beta plasmatic phases were found to be equal at 3.79 and 41.4 min in dialysed subjects and at 1.13 and 16.54 in healthy volunteers. These results indicate that in uremic patients undergoing dialysis at intervals using defibrotide, a longer time is required to eliminate the drug from the circulation. This variation does not however appear to be significant in terms of the therapeutic use of the drug during dialysis.

    1998-05-01

    Objective: CT of the chest in paediatric patients often requires sedation or general anaesthesia to minimize motion artefacts. Both sedation and general anaesthesia are associated with atelectasis which obscures the underlying pulmonary pathology. We conducted a prospective study to compare these two methods with respect to degree of motion artefacts and extent of atelectasis. Material and Methods: Nineteen patients undergoing 22 chest CT examinations were randomly selected for either sedation or general anaesthesia. The total area of atelectasis and the degree of motion artefacts were measured. Results: The mean percentage of atelectasis was 6.67% for general anaesthesia and 0.01% for sedation (p=0.01). There was no significant difference in the quality of the images between the sedation patients and the general anaesthesia patients. Conclusion: Whenever the clinical condition permits it, sedation rather than general anaesthesia should be given to paediatric patients undergoing chest CT. (orig.).

    The elderly patient undergoing dialysis is often at risk of undernutrition. The condition may already be present at the pre-dialysis stage and can worsen once dialysis starts. Aside from the impact on the patient's quality of life and general health status, undernutrition exposes them to serious risk of complications and can be life-threatening. It is therefore essential that it is diagnosed early. Copyright © 2015 Elsevier Masson SAS. All rights reserved.

    2015-09-01

    Full Text Available The incidence and prevalence of cardiovascular disease (CVD are increasing rapidly in developing countries. Most patients with CVD do not respond to medical treatment and have to undergo cardiac surgery. This highly stressful experience results in increased levels of anxiety for patients. The objective of this review was to evaluate the efficacy of massage therapy on postoperative outcomes among patients undergoing cardiac surgery. A comprehensive literature search was made on PubMed-Medline, CINAHL, Science Direct, Scopus, Web of Science and the Cochrane library databases for original research articles published between 2000 and 2015. Original articles that reported the efficacy of massage therapy in patients undergoing cardiac surgery were included. The Cochrane data extraction form was used to extract data. A total of 297 studies were identified in the literature search. However, only seven studies were eligible for analysis. Of the seven studies, six studies demonstrated the effects of massage therapy on improving post-operative outcomes of patients, while one study found no evidence of improvement. Although the methods varied considerably, most of the studies included in this review reported positive results. Therefore, there is some evidence that massage therapy can lead to positive postoperative outcomes. Evidence of the effectiveness of massage therapy in patients undergoing cardiac surgery remains inconclusive. Additional research is needed to provide a strong evidence base for the use of massage therapy to improve post-operative outcomes and recovery among cardiac surgery patients

    Objectives This study aimed to review general anaesthesia protocols for patients undergoing electroconvulsive therapy (ECT) at a tertiary care hospital in Oman, particularly with regards to clinical profile, potential drug interactions and patient outcomes. Methods This retrospective study took place at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. The electronic medical records of patients undergoing ECT at SQUH between January 2010 and December 2014 were reviewed for demographic characteristics and therapy details. Results A total of 504 modified ECT sessions were performed on 57 patients during the study period. All of the patients underwent a uniform general anaesthetic regimen consisting of propofol and succinylcholine; however, they received different doses between sessions, as determined by the treating anaesthesiologist. Variations in drug doses between sessions in the same patient could not be attributed to any particular factor. Self-limiting tachycardia and hypertension were periprocedural complications noted among all patients. One patient developed aspiration pneumonitis (1.8%). Conclusion All patients undergoing ECT received a general anaesthetic regimen including propofol and succinylcholine. However, the interplay of anaesthetic drugs with ECT efficacy could not be established due to a lack of comprehensive data, particularly with respect to seizure duration. In addition, the impact of concurrent antipsychotic therapy on anaesthetic dose and subsequent complications could not be determined. PMID:28417028

    ABSTRACT Purpose: To identify the educational needs of adults who undergo total hip and total knee replacement surgery. Methods: A qualitative research design using a semi-standardized interviewing method was employed. A purposive sampling technique was used to recruit participants, who were eligible if they were scheduled to undergo total hip or total knee replacement or had undergone total hip or total knee replacement in the previous 3 to 6 months. A comparative contrast method of analysis was used. Results: Of 22 potential participants who were approached, 15 participated. Five were booked for upcoming total hip or total knee replacement and 10 had undergone at least one total hip or total knee replacement in the previous 3 to 6 months. Several themes related to specific educational needs and factors affecting educational needs, including access, preoperative phase, surgery and medical recovery, rehabilitation process and functional recovery, fears, and expectations counterbalanced with responsibility, emerged from the interviews. Conclusions: Educational needs of adults who undergo total hip and knee replacement surgery encompass a broad range of topics, confirming the importance of offering an all-inclusive information package regarding total hip and total knee replacement.

    Sinusitis is a common morbidity in general population, however little is known about its occurrence in severely immunocompromised patients undergoing allogeneic hematopoietic stem cell transplantation. The aim of the study was to analyze the literature concerning sinusitis in patients undergoing allogeneic bone marrow transplantation. An electronic database search was performed with the objective of identifying all original trials examining sinusitis in allogeneic hematopoietic stem cell transplant recipients. The search was limited to English-language publications. Twenty five studies, published between 1985 and 2015 were identified, none of them being a randomized clinical trial. They reported on 31-955 patients, discussing different issues i.e. value of pretransplant sinonasal evaluation and its impact on post-transplant morbidity and mortality, treatment, risk factors analysis. Results from analyzed studies yielded inconsistent results. Nevertheless, some recommendations for good practice could be made. First, it seems advisable to screen all patients undergoing allogeneic hematopoietic stem cell transplantation with Computed Tomography (CT) prior to procedure. Second, patients with symptoms of sinusitis should be treated before hematopoietic stem cell transplantation (HSCT), preferably with conservative medical approach. Third, patients who have undergone hematopoietic stem cell transplantation should be monitored closely for sinusitis, especially in the early period after transplantation.

    Patients undergoing gastrointestinal operations are at risk of malnutrition which may increase the chance of adverse surgical outcomes. This prospective study aimed at correlating nutritional status of patients having gastrointestinal operations with their short-term surgical outcomes captured by a territory-wide Surgical Outcomes Monitoring and Improvement Program. The preoperative malnutrition risk of Chinese adult patients undergoing elective/emergency ultra-major/major gastrointestinal operations in two surgical departments over a 12-month period were assessed by Chinese version of Malnutrition Universal Screening Tool. Their perioperative risk factors and clinical outcomes, including length of hospital stay, mortality and morbidity, were retrieved from the above mentioned program. Correlation of malnutrition risk with clinical outcomes was assessed by logistic regression analysis after controlling for known confounders. 943 patients (58% male; mean age 65.9 ± 14.8 years) underwent gastrointestinal operations (40.3% emergency operation; 52.7% ultra-major procedures; 66.9% bowel resections) had analyzable data. 15.8% and 17.1% of patients were at medium and high risk of malnutrition, respectively. Malnutrition risk score according to the screening tool was an independent predictor of length of hospital stay, 30-day mortality, 60-day mortality and minor medical complications. Similar correlations were found for various sub-scores of malnutrition risk. Weight loss sub-score was predictive of 30-day mortality, 60-day mortality and minor medical complications. Body mass index was predictive of mortality (30- and 60- day) whereas the acute disease sub-score was predictive of length of hospital stay. Preoperative malnutrition was an important predictor of poor clinical outcomes in patients undergoing gastrointestinal operations in Hong Kong.

    AIM:To investigate whether the incidence of hiccups in patients undergoing esophagogastroduodenoscopy (EGD) or same-day bidirectional endoscopy (EGD and colonoscopy; BDE) with sedation is different from those without sedation in terms of quantity,duration and typical onset time.METHtODS:Consecutive patients scheduled for elective EGD or same-day BDE at the gastrointestinal endoscopy unit or the health examination center were allocated to two groups:EGD without sedation (Group A)and BDE with sedation (Group B).The use of sedation was based on the patients' request.Anesthesiologists participated in this study by administrating sedative drugs as usual.A single experienced gastroenterologist performed both the EGD and the colonoscopic examinations for all the patients.The incidence,duration and onset time of hiccups were measured in both groups.In addition,the association between clinical variables and hiccups were analyzed.RESULTS:A total of 435 patients were enrolled in the study.The incidences of hiccups in the patients with and without sedation were significantly different (20.5% and 5.1%,respectively).The use of sedation for patients undergoing endoscopy was still significantly associated with an increased risk of hiccups (adjusted odds ratio:8.79,P < 0.001) after adjustment.The incidence of hiccups in males under sedation was high (67.4%).The sedated patients who received 2 mg midazolam developed hiccups more frequently compared to those receiving 1 mg midazolam (P =0.0028).The patients with the diagnosis of gastroesophageal reflux disease (GERD) were prone to develop hiccups (P =0.018).CONCLUSION:Male patients undergoing EGD or BDE with sedation are significantly more likely to suffer from hiccups compared to those without sedation.Midazolam was significantly associated with an increased risk of hiccups.Furthermore,patients with GERD are prone to develop hiccups.

    To identify factors associated with the use of axillary lymph node dissection (ALND) as the initial axillary staging in node-negative breast cancer patients undergoing total mastectomy. California Cancer Registry study. Academic research. Women treated with total mastectomy for Tis, T1, or T2 node-negative breast carcinoma treated between January 1, 2004, and December 31, 2008. Proportions of patients who underwent ALND without prior sentinel lymph node dissection were compared by demographic characteristics. Of 18,238 women treated with total mastectomy for Tis, T1, or T2 node-negative breast carcinoma, 35.1% underwent initial axillary staging by ALND without prior sentinel lymph node dissection. On multivariable analyses, patients were significantly more likely to undergo ALND if they had T2 disease or were 65 years or older, were hormone receptor negative, of Hispanic or Asian/Pacific Islander race/ethnicity, of lower socioeconomic quintile, operated on during earlier years of the study period, and not treated by a hospital cancer program approved by the American College of Surgeons. More than one-third of patients in California who underwent total mastectomy for treatment of early-stage node-negative breast carcinoma received ALND without prior sentinel lymph node dissection; furthermore, certain subsets of patients have higher odds of undergoing ALND alone. To avoid the unnecessary morbidity of ALND in early-stage breast carcinoma, further research is required to elucidate how tumor, patient, and system factors can be modified to improve delivery of optimal breast cancer care.

    Alcoholic cirrhotics evaluated for liver transplantation are frequently malnourished or obese. We analyzed alcoholic cirrhotics undergoing transplantation to examine time trends of nutrition/weight, transplant outcome, and effects of concomitant hepatitis C virus (HCV) and/or hepatocellular carcinoma (HCC). Nutrition and transplant outcomes were reviewed for alcoholic cirrhosis with/without HCV/HCC. Malnutrition was defined by subjective global assessment. Body mass index (BMI) classified obesity. A total of 261 patients receiving transplants were separated (1988-2000, 2001-2006, and 2007-2011) to generate similar size cohorts. Mean BMI for the whole cohort was 28 ± 6 with 68% classified as overweight/obese. Mean BMI did not vary among cohorts and was not affected by HCV/HCC. While prevalence of malnutrition did not vary among cohorts, it was lower in patients with HCV/HCC (P graft/patient survival was 90% and not impacted by time period, HCV/HCC, or malnutrition after adjusting for demographics and model end-stage liver disease (MELD). Alcoholic cirrhotics undergoing transplantation are malnourished yet frequently overweight/obese. Among patients selected for transplantation, 1-year post-transplant graft/patient survival is excellent, have not changed over time, and do not vary by nutrition/BMI. Our findings support feasibility of liver transplantation for alcoholic cirrhotics with obesity and malnutrition.

    Introduction Tertiary hyperparathyroidism (3HPTH) patients who undergo parathyroidectomy are often managed with calcium lowering medications such as cinacalcet (Sensipar®) preceding surgery. Here, we assess how cinacalcet (Sensipar®) treatment influences intraoperative PTH (IOPTH) kinetics and surgical findings in 3HPTH patients undergoing parathyroidectomy. Methods 116 retrospectively reviewed 3HPTH patients underwent, parathyroidectomy of which 14 were on cinacalcet and 112 were on no drug. IOPTH levels fitted to linear curves vs. time were used to evaluate the role of cinacalcet. Results Cinacalcet did not significantly correlate with rates of cure (p=0.41) or recurrence (p=0.54). Patients on cinacalcet experienced a significantly steeper decline in IOPTH compared to those not on medication (p=0.005). Cinacalcet treatment was associated with a significant increase in rate of hungry bones (p=0.04). Weights of the heaviest glands resected (p=0.02) and preoperative PTH levels (p=0.0004) were significantly higher among patients on cinacalcet. Conclusions Perioperative cinacalcet treatment in 3HPTH patients alters IOPTH kinetics by causing a steeper IOPTH decline, but does not require modifying standard IOPTH protocol. Although cinacalcet use does not adversely affect cure rates, it is associated with higher preoperative PTH and an increased incidence of hungry bones, hence serving as an indicator of more severe disease. Cinacalcet does not need to be held prior to surgery. PMID:25456900

    Background: Evaluation of the efficacy and safety of a new 7F-atherectomy device (30-day endpoint) for the treatment of short and mid-length arterial lesions with a reference diameter of 2.5-7 mm. Material and Methods: Fifty-eight femoto-popliteal stenoses in 46 patients (67% male, mean age 66{+-} 9 years) with chronic peripheral occlusive disease of the lower limbs [Rutherford stage 2: n = 13 (28%); stage 3: n = 29 (63%); stage 4: 2 (4%), stage 5: n = 2 (4%]), were treated with directional atherectomy. Target lesion characteristics: Common femoral artery: n = 1 (2%), superficial femoral artery: n = 47 (81%); popliteal artery, n = 10 (17%); instent n = 3 (5%). Thirty (65%) of the interventions were performed using an antegrade approach, 16 (35%) interventions in cross-over technique. Mean degree of stenosis was 83 {+-} 11 mm, mean length of lesion was 37 {+-} 37 mm. Results: 6.5 {+-} 2 (4-10) passes of the lesion were performed with the catheter. Three lesions were treated after predilatation, 55 (95%) interventions as primary atherectomy. In 31/58 lesions (53%) additional balloon angioplasty was performed, in 1 lesion (2%) additional stent placement was needed. The mean degree of stenosis after atherectomy was reduced to 29 {+-} 20% (0-60%) after additional balloon angioplasty, it was 11 {+-} 10% (0-30%). A residual stenosis of < 50% after plain atherectomy was achieved in 55 (95%) lesions, of < 30% in 49 (84%). Complications: 3 (6,5%) cases of embolism of debris were detected and treated successfully by aspiration. The mean ankle-brachial index increased from 0.62 {+-} 0.12 to 0.92 {+-} 0.36 before discharge, and to 0.86 {+-} 0.17 after 30 days.

    Full Text Available Abstract Background Sexual function among women undergoing hemodialysis (HD is under-studied and there is no consensus about the effect of sexual dysfunction (SD on their quality of life (QoL. We aimed to determine the prevalence of SD and to compare QoL between women undergoing maintenance HD with and without SD. Methods We included female end-stage renal disease (ESRD patients undergoing HD during June 2011 in the only renal unit in the north of Ceará state, northeastern Brazil. The criteria for inclusion were age between 18 and 55, at least three months on dialysis and being sexually active. Women using antidepressant medication were excluded. We used the Female Sexual Function Index (FSFI, which evaluates six domains of sexual function, including desire, arousal, lubrication, orgasm, satisfaction and pain. The patients were classified as presenting SD if the total FSFI score was less than 26. For QoL evaluation, we used the validated Brazilian version of SF-36. This is a widely used 36-item questionnaire covering eight dimensions of QoL. Demographic data, time on dialysis, underlying etiology of ESRD, and laboratory measures were assessed in unit records. Results Of a total of 58 women, 46 (79.3% presented SD. There were lower scores related to physical functioning (48.2 vs. 71.2; p = 0.007, bodily pain (45 vs. 67.5; p = 0.010, vitality (52.1 vs. 69.1; p = 0.026 and social functioning (57.2 vs. 76.1; p = 0.034 among women with SD compared to women without SD. Physical functioning and role-physical presented positive linear correlation with FSFI scores, respectively, r = 0.322 (p = 0.013 and r = 0.345 (p = 0.007. Conclusion The prevalence of SD among women on HD is very high, reaching nearly 80%. Women on HD with SD had worse QoL, especially physical aspects of QoL, when compared to women without SD. Therefore, approaches aiming to improve QoL among women undergoing HD should be considered.

    Full Text Available Objective: An inter-relationship between periodontal disease and systemic health has been suspected for centuries, but evidence to explain the connection has only been elucidated in the past few decades. Among the systemic diseases, end stage renal disease has been shown to affect not only the general health of the patient but also oral and periodontal health. This study was undertaken to gain an insight into whether duration of dialysis therapy influences the oral and periodontal health of these patients and also to see if these parameters reflect their biochemical values. Materials and Methods: The study was conducted on 75 patients undergoing dialysis and a control group of 25 subjects. The study group was divided into three subgroups depending upon the duration of dialysis. Oral hygiene and periodontal disease status were measured by Simplified Oral Hygiene Index by Greene and Vermillion and Periodontal Disease Index by Ram-fjord. Biochemical parameters measured were blood urea nitrogen and salivary urea levels. Comparison of these parameters was made between the study and control groups through analysis of variance (ANOVA and student′s t-test. Results: Prevalence of periodontal disease was evident in the dialysis group. Oral hygiene status was poor in comparison with the control group. Clinical and biochemical parameters showed statistically significant difference between the groups rather than within the groups. Conclusion: Oral and periodontal health appeared to be compromised. Their deteriorating general health is anticipated to cause negligence towards oral health care. This population needs comprehensive oral and periodontal care right from the diagnosis of chronic renal failure. There exists a need for communication between nephrologists and oral health care professionals. Longitudinal studies warranted in this regard.

    Currently we know not more than 50 patients who show an interesting combination of increased plasma ornithine concentrations, postprandial hyperammonemia, and homocitrullinuria (HHH-syndrome). Since exact knowledge of this severe, although rare syndrome is important for any perioperative or intensive medical treatment concerning therapy and progression of the disease, we report a comprehensive study on a 32-year old woman with this rare multifaceted disorder who had to undergo general anaesthesia. For the first time amino acid status in plasma, urine, cerebrospinal fluid and especially polymorphonuclear leucocytes, which in the investigation showed to be valuable tool for evaluating amino acid metabolism in nucleated cells in HHH-syndrome, and further important pathophysiologic indicators of cellular and metabolic function have been conscientiously investigated and compared. The pathophysiological repercussions of our results as well as the recommendations for conscientious therapeutical management are discussed.

    Research indicates that slow heart rate recovery 1-2 minutes after exercise is a predictor of cardiovascular mortality, sudden mortality as well. It is hardly related to myocardial ischemia; most of all, it is related to impaired activities of the parasympathetic system. The purpose of this study was to assess HRR in subjects after a surgical treatment (percutaneous coronary intervention - PCI) of acute coronary syndromes (ACS), undergoing cardiologic rehabilitation. The study comprised 58 subjects, 42 men and 16 women aged 49-68 (56.8 +/- 7.6) after ACS treated with PCI undergoing cardiologic rehabilitation (stage 2)--group I. The comparative group comprised 34 subjects, 25 men and 9 women aged 46-61 (55.5 +/- 8.9 lat) who were clinically healthy and who underwent a single sub-maximal exercise test--group II. In subjects undergoing rehabilitation, an exercise test was performed twice --before and after stage 2 of rehabilitation. HRR was defined as a difference between the peak heart rate and those after the 1st (HRR1) and 2nd (HRR) minute of recovery. After stationary rehabilitation as a part of stage 2 of cardiologic rehabilitation, HRR2 was 26.3 +/- 10.6/min and was 40.8/min +/- 13.8/min; both these values were not significantly different from values observed in healthy subjects (p > 0.05). Significant increase in HRR1 and HRR2 was observed after the completion of stage 2 of cardiologic rehabilitation in ill subjects (p < 0.05) as compared to initial values. In subjects after ACS treated with PCI, it is observed that HRR changes back to normal values observed in healthy subjects as a result of underwent cardiologic rehabilitation. HRR should become an important factor in assessing effectiveness of conducted cardiologic rehabilitation.

    While there are many reported advantages to laparoscopic surgery compared to open surgery, the impact of a laparoscopic approach on postoperative morbidity in obese patients undergoing rectal surgery has not been studied. Our goal was to determine whether obese patients undergoing laparoscopic rectal surgery experienced the same benefits as non-obese patients. We identified patients undergoing rectal resections using the National Surgical Quality Improvement Project Participant Use Data File. We performed multivariable analyses to determine the independent association between laparoscopy and postoperative complications. A total of 26,437 patients underwent rectal resection. The mean age was 58.5 years, 32.6 % were obese, and 47.2 % had cancer. Laparoscopic procedures were slightly less common in obese patients compared to non-obese patients (36.0 vs. 38.2 %, p = 0.0006). In unadjusted analyses, complications were lower with the laparoscopic approach in both obese (18.9 vs. 32.4 %, p obese (15.6 vs. 25.3 %, p obesity worsened. The likelihood of experiencing a postoperative complication increased by 25, 45, and 75 % for obese class I, obese class II, and obese class III patients, respectively. A laparoscopic approach was associated with a 40 % decreased odds of a postoperative complication for all patients (OR 0.60, 95 % CI 0.56-0.64). Laparoscopic rectal surgery is associated with fewer complications when compared to open rectal surgery in both obese and non-obese patients. Obesity was an independent risk factor for postoperative complications. In appropriately selected patients, rectal surgery outcomes may be improved with a minimally invasive approach.

    AIM: To compare creatinine clearance (Ccr) with estimated glomerular filtration rate (eGFR) in preoperative renal function tests in patients undergoing hepatectomy. METHODS: The records of 197 patients undergoing hepatectomy between August 2006 and August 2008 were studied, and preoperative Ccr, a three-variable equation for eGFR (eGFR3) and a five-variable equation for eGFR (eGFR5) were calculated. Abnormal values were defined as Ccr < 50 mL/min, eGFR3 and eGFR5 < 60 mL/min per 1.73 m2. The maximum increases in the postoperative serum creatinine (post Cr) level and postoperative rate of increase in the serum Cr level (post Cr rate) were compared. RESULTS: There were 37 patients (18.8%) withabnormal Ccr, 31 (15.7%) with abnormal eGFR3, and 40 (20.3%) with abnormal eGFR5. Although there were no significant differences in the post Cr rate between patients with normal and abnormal Ccr, eGFR3 and eGFR5 values, the post Cr level was significantly higher in patients with eGFR3 and eGFR5 abnormality than in normal patients ( P < 0.0001). Post Cr level tended to be higher in patients with Ccr abnormality ( P = 0.0936 and P = 0.0875, respectively). CONCLUSION: eGFR5 and the simpler eGFR3, rather than Ccr, are recommended as a preoperative renal function test in patients undergoing hepatectomy.

    Full Text Available ABSTRACT INTRODUCTION: The currently common musculoskeletal disorders have been increasingly treated surgically, and the pain can be a limiting factor in postoperative rehabilitation. RATIONALE: Patient controlled analgesia (PCA controls pain, but its adverse effects can interfere with rehabilitation and in the patient discharge process. This study becomes important, since there are few studies evaluating this correlation. OBJECTIVES: To compare the outcomes of patients who used and did not use patient controlled analgesia in postoperative orthopedic surgery with respect to pain, unscheduled need for O2 (oxygen, and time of immobility and in-hospital length of stay. METHODS: This is an observational, prospective study conducted at Hospital Abreu Sodré from May to August 2012. The data was daily obtained through assessments and interviews of patients undergoing total hip arthroplasty (THA and total knee arthroplasty (TKA, thoracolumbar spine arthrodesis (long PVA, cervical spine arthrodesis (cervical AVA and lumbar spine arthrodesis (lumbar PVA. RESULTS: The study showed some differences between groups, namely: the painful level was higher in the group undergoing lumbar PVA without PCA compared with the group with PCA (p = 0.03 and in the group of long PVA without PCA in the early postoperative period. This latter group used O2 for a longer time (p = 0.09. CONCLUSION: In this study, PCA was useful for analgesia in patients undergoing lumbar PVA and probably would have influenced the usage time of O2 in the group of long PVA in face of a larger sample. The use of PCA did not influence the time of leaving the bed and the in-hospital length of stay for the patients studied.

    Full Text Available Aim: To estimate the incidence of VTE in Indonesian patients undergoing major orthopedic surgery and not receiving thromboprophylaxis.Methods: This was an open clinical study of consecutive Indonesian patients undergoing major orthopedic surgery, conducted in 3 centers in Jakarta. Bilateral venography was performed between days 5 and 8 after surgery to detect the asymptomatic and to confi rm the symptomatic VTE. These patients were followed up to one month after surgery.Results: A total of 17 eligible patients were studied, which a median age of 69 years and 76.5% were females. Sixteen out of the 17 patients (94.1% underwent hip fracture surgery (HFS. The median time from injury to surgery was 23 days (range 2 to 197 days, the median duration of surgery was 90 minutes (range 60 to 255 minutes, and the median duration of immobilization was 3 days (range 1 to 44 days. Thirteen out of the 17 patients were willing to undergo contrast venography. A symptomatic VTE was found in 9 patients (69.2% at hospital discharge. Symptomatic VTE was found in 3 patients (23.1%, all corresponding to clinical signs of DVT and none with clinical sign of PE. These patients were treated initially with a low molecular weight heparin, followed by warfarin. Sudden death did not occur up to hospital discharge. From hospital discharge until 1-month follow-up, there were no additional cases of symptomatic VTE. No sudden death, bleeding complication, nor re-hospitalization was found in the present study.Conclusion: The incidence of asymptomatic (69.2% and symptomatic (23.1% VTE after major orthopedic surgery without thromboprophylaxis in Indonesian patients (SMART and AIDA, and still higher than the results of the Western studies. A larger study is required to establish the true incidence, and more importantly, that the use of thromboprophylaxis in these patients is warranted.

    Hemolysis is a common complication of extracorporeal membrane oxygenation (ECMO) support and is associated with increased mortality. Frequent monitoring of markers of hemolysis is performed at ECMO centers. We report two cases of spurious hemolysis caused by hypertriglyceridemia in patients undergoing ECMO support. Critically ill patients, including those receiving ECMO, may be at risk of developing medication-induced hypertriglyceridemia. The interference of lipids with the measurement of plasma free hemoglobin, a marker of hemolysis, should be recognized. Our cases highlight the importance of investigating hypertriglyceridemia as part of the assessment of unexplained hemolysis in patients supported with ECMO. © The Author(s) 2014.

    Otorhinolaryngologists began developing new operative techniques to minimize open surgical resections of the head and neck. While striving to reduce the morbidity and mortality associated with head and neck surgery and decrease the many psychosocial issues facing these patients, a new procedure defined as Transoral Robotic Surgery (TORS) was developed. With the development of new surgical techniques, nursing care must also change to meet the needs of the patient. As the TORS procedure becomes fully defined, so is nursing's role in the care of the patient. This paper aims to define TORS and discuss the nursing care of the patient undergoing this new surgical procedure.

  18. Modeling Study of Planar Flexible Manipulator Undergoing Large Deformation

    Institute of Scientific and Technical Information of China (English)

    2007-01-01

    The planar flexible manipulator undergoing large deformation is investigated by using finite element method (FEM). Three kinds of reference frames are employed to describe the deformation of arbitrary point in the flexible manipulator, which are global frame, body-fixed frame and co-rotational frame. The rigid-flexible coupling dynamic equation of the planar flexible manipulator is derived using the Hamilton's principle. Numerical simulations are carried out in the end of this paper to demonstrate the effectiveness of the proposed model. The simulation results indicate that the proposed model is efficient not only for small deformation but also for large deformation.

    Sedation plays a central role in making colonoscopy tolerable for patients and feasible for the endoscopist to perform. The array of agents used for endoscopic sedation continues to evolve. Fospropofol (FP), a prodrug of propofol with a slower pharmacokinetic profile, is currently under evaluation for use during endoscopic procedures. Preliminary data suggests that FP dosed at 6.5 mg/kg is well tolerated by most patients with perineal paresthesias being the most commonly experienced adverse effect. This article will examine the current literature on the use of FP for the sedation of patients undergoing colonoscopy, highlighting the pharmacokinetics, pharmacodynamics, risks, and common adverse events associated with the novel sedative/hypnotic.

    Study Design Retrospective database analysis. Objective To assess the effect glycemic control has on perioperative morbidity and mortality in patients undergoing elective degenerative lumbar spine surgery. Summary of background data Diabetes Mellitus (DM) is a prevalent disease of glucose dysregulation that has been demonstrated to increase morbidity and mortality following spine surgery. However, there is limited understanding of whether glycemic control influences surgical outcomes in DM patients undergoing lumbar spine procedures for degenerative conditions. Methods The Nationwide Inpatient Sample was analyzed from 2002 to 2011. Hospitalizations were isolated based on International Classification of Diseases Ninth Revision, Clinical Modification procedural codes for lumbar spine surgery and diagnoses codes for degenerative conditions of the lumbar spine. Patients were then classified into three cohorts: controlled diabetics, uncontrolled diabetics and non-diabetics. Patient demographic data, acute complications and hospitalization outcomes were determined for each cohort. Results A total of 403,629 (15.7%) controlled diabetics and 19,421(0.75%) uncontrolled diabetics underwent degenerative lumbar spine surgery from 2002-2011. Relative to non-diabetics, uncontrolled diabetics had significantly increased odds of cardiac complications, deep venous thrombosis and post-operative shock; additionally, uncontrolled diabetics also had an increased mean length of stay (approximately 2.5 days), greater costs (1.3-fold) and a greater risk of inpatient mortality (odds ratio=2.6, 95% confidence interval=1.5-4.8, p degenerative lumbar spine surgery leads to increased risk of acute complications and poor outcomes. Patients with uncontrolled DM, or poor glucose control, may benefit from improving glycemic control prior to surgery. PMID:24983935

    Full Text Available Like rheumatoid arthritis, ankylosing spondylitis (AS is also an inflammatory disease associated with accelerated atherosclerosis and the presence of metabolic syndrome (MeS features. AS patients often display osteoporosis as well as new bone formation. Insulin-like growth factor 1 (IGF-1 is a protein involved in both inflammation and bone metabolism. In the present study we assessed whether disease activity, systemic inflammation, MeS features, adipokines, and biomarkers of endothelial activation were associated with IGF-1 and insulin-like growth factor binding protein-3 (IGFBP-3 levels in a series of 30 nondiabetic AS patients without CV disease undergoing TNF-α antagonist-infliximab therapy. All determinations were made in the fasting state, immediately before an infliximab infusion. Although no association of IGF-1 and IGFBP-3 levels with angiopoietin-2 or osteopontin was found, an inverse correlation between IGF-1 levels and asymmetric dimethylarginine (ADMA, an endogenous endothelial nitric oxide synthase inhibitor that impairs nitric oxide production and secretion promoting endothelial dysfunction, was found (r=-0.397; P=0.04. However, no significant association was found between IGF-1 and IGFBP-3 levels and disease activity, systemic inflammation, metabolic syndrome features, or adipokines. In conclusion, in nondiabetic patients with AS undergoing periodic anti-TNF-α therapy, IGF-1 and ADMA are inversely correlated.

    Objective To investigate a recent association between use of the angiotensin receptor-blocker (ARB) olmesartan and a severe enteropathy resembling celiac disease. Patients and Methods We searched our endoscopy database for all outpatient esophagogastroduodenoscopy (EGD) or colonoscopy examinations in patients at least 50 years of age during the dates January 1, 2007 to March 31, 2013. Cases were those whose examination indication was diarrhea, and controls were those whose examination indication was esophageal reflux (EGD) or colorectal cancer screening (colonoscopy). We compared cases to controls with regard to the proportion of those listing olmesartan among their medications. Secondary exposures were the proportion of those taking non-olmesartan ARBs or other anti-hypertensive medications. We also examined biopsy results to determine if there were histologic changes associated with olmesartan use. Results We identified 2088 patients undergoing EGD and 12428 patients undergoing colonoscopy meeting inclusion criteria. On multivariate analysis, there was no statistically-significant association between olmesartan and diarrhea among those undergoing EGD (OR 1.99 95% CI 0.79–5.00) or colonoscopy (OR 0.63 95% CI 0.23–1.74). Review of pathology reports of the EGD and colonoscopy groups showed no association between olmesartan use and the histologic diagnosis of celiac disease (p=0.61) or microscopic colitis (p=1.0), respectively. Conclusions Our findings suggest that neither olmesartan nor other ARBs were associated with diarrhea among patients undergoing endoscopy. The sprue-like enteropathy recently associated with olmesartan is likely a rare adverse effect and milder presentations are unlikely. PMID:25023670

    Heart failure is an established risk factor for poor outcomes in patients undergoing non-cardiac surgery, yet risk stratification remains a clinical challenge. We developed an index for 30-day mortality risk prediction in this particular group. All individuals with heart failure undergoing non-cardiac surgery between October 23 2004 and October 31 2011 were included from Danish administrative registers (n = 16 827). In total, 1787 (10.6%) died within 30 days. In a simple risk score based on the variables from the revised cardiac risk index, plus age, gender, acute surgery, and body mass index category the following variables predicted mortality (points): male gender (1), age 56-65 years (2), age 66-75 years (4), age 76-85 years (5), or age >85 years (7), being underweight (4), normal weight (3), or overweight (1), undergoing acute surgery (5), undergoing high-risk procedures (intra-thoracic, intra-abdominal, or suprainguinal aortic) (3), having renal disease (1), cerebrovascular disease (1), and use of insulin (1). The c-statistic was 0.79 and calibration was good. Mortality risk ranged from 50% for a score ≥20. Internal validation by bootstrapping (1000 re-samples) provided c-statistic of 0.79. A more complex risk score based on stepwise logistic regression including 24 variables at P < 0.05 performed only slightly better, c-statistic = 0.81, but was limited in use by its complexity. For patients with heart failure, this simple index can accurately identify those at low risk for perioperative mortality. © 2014 The Authors European Journal of Heart Failure © 2014 European Society of Cardiology.

    Objectives Early and accurate diagnosis of peripheral atherosclerosis is of paramount importance for global managerment of patients with known coronary artery disease (CAD), especially in the elderly. We sought to evaluate the prevalence and clinical relevance of significant abdominal vessel stenosis or aneurysm (AVA) in patients undergoing coronary angiography. Methods Medical records of consecutive > 75-year old patients who underwent coronary angiography at two public institutions over a 12-month period were evaluated. Angiographic results of patients who underwent coincident diagnostic abdominal aorta angiography to evaluate abdominal vessels on the basis of clinical and angiographic criteria were analyzed. Results During the study period, AVA was found in 90 (35.7% ) of 252 consecutive patients (185 males, mean age 79±5.8 years), renal artery stenosis in 13.1% of cases (33 patients), aortoiliac artery disease in 13.7 % (35 patients), and aortic aneurismal disease in 8.9% (22 patients). Logistic regression analyses revealed > 3-vessel CAD (odds ratio [OR] :9.917, P = 0.002), and > 3 risk factors (OR: 2.8, P =0. 048) as independent predictors of AVA. Conclusions Aged patients with multivessel CAD frequently have a high risk profile and multiple vascular atherosclerotic distributions, suggesting the usefulness of a mere global and comprehensive cardiovascular approach in aged patients.

    The assessment of the cardiovascular risk profile in patients with end-stage liver disease is essential prior to liver transplantation (LT) as cardiovascular diseases are major causes of morbidity and mortality in the posttransplant course. The aim of this study was to evaluate the accuracy of a 64-slice coronary computed tomographic angiography (CTA) and coronary calcium scoring (CCS) to predict the postoperative cardiovascular risk of patients assessed for LT. In this single center, observational study we included 54 consecutive patients who were assessed for LT and consequently transplanted. Twenty-four patients (44%) presented with a high CCS above 300 and/or a significant stenosis (>50% percent narrowing due to stenotic plaques) and were further referred to coronary angiography. Three of these patients had a more than 70% LAD stenosis with subsequent angioplasty (n = 1) or conservative therapy (n = 2). The other patients showed only diffuse CAD without significant stenosis. The remaining 30 patients with normal CTA findings were listed for LT without further tests. None of the 54 patients developed cardiovascular events peri- and postoperatively. This study indicated that CTA combined with CCS is a useful non-invasive imaging technique for pre-LT assessment of coronary artery disease and safe tool in the risk assessment of peri- and postoperative cardiovascular events in patients undergoing LT.

    Many stroke patients may have oral problems and systemic diseases, but clinical information on treatment provided to stroke patients for dental problems during inpatient rehabilitation is rare. The objective of this study was to research stroke inpatients' requirements for dental treatment and the accompanying risks. We included 165 stroke patients undergoing inpatient rehabilitation at Morinomiya Hospital during the year 2010 and researched the causes of stroke and the patients' orodental status, underlying diseases, antithrombotic drugs prescribed and special considerations or difficulties in the treatment. Cerebral infarction was the most common causes of stroke. Many patients had hypertension, heart disease or diabetes mellitus, and 54.5% had been prescribed antithrombotic drugs. Dentists diagnosed 57.0% patients with untreated dental cavities. Approximately 30% did not use dentures despite having a requirement. In total, 142 patients underwent dental treatment including periodontal treatment, prosthetic treatment and tooth extraction under management of circulation and haemostasis such as monitoring vital signs and surgical splints in cases of the difficult extraction. The current study revealed a high requirement for dental treatment among stroke patients and demonstrated the effectiveness of performing dental treatment during inpatient rehabilitation of these patients. © 2014 John Wiley & Sons A/S and The Gerodontology Society.

    2012-06-01

    Disease recurrence following resective surgery for Crohn disease remains a challenging clinical problem, and more studies are needed to better define risk stratification and treatment recommendations in the postoperative setting. Endoscopy remains the gold standard for the assessment of postoperative disease recurrence, and all Crohn disease patients who undergo surgery should undergo ileocolonoscopy within 6 to 12 months of surgery. The degree of endoscopic recurrence in the neoterminal ileum during this procedure provides prognostic information regarding the severity of the future disease course. WCE, MRE, and SICUS are all promising noninvasive modalities to assess for postoperative Crohn disease activity. However, further studies are needed to better define scoring systems, operating characteristics and variability, and prognostic data for each of these modalities. In patients at risk for early disease recurrence, more aggressive prophylactic therapy should be considered, in hopes of delivering true “top-down” therapy that may offer maximum impact in altering the natural history of Crohn disease.

    To evaluate the effect of furosemide on cardiovascular hemodynamics in patients with end-stage renal failure, we studied ten patients undergoing hemodialysis three times a week. Arterial pressure, heart rate, and cardiac output (indocyanine green dye) were measured in triplicate; total peripheral resistance and central blood volume were calculated by standard formulas. Hemodynamics were determined at baseline and 5, 10, 15, and 30 minutes after intravenous (IV) bolus injection of furosemide 60 mg. Furosemide produced a decrease in central blood volume of -13% +/- 2.2% from pretreatment values (P less than .01) that was most pronounced five minutes after injection, together with a fall in cardiac output (from 6.76 +/- 0.59 to 6.17 +/- 0.52 L/min, P less than .10). Stroke volume decreased with a maximum fall occurring after 15 minutes (from 84 +/- 7 to 79 +/- 7 mL/min, P less than .05), and total peripheral resistance increased (from 15.8 +/- 2.1 to 17.8 +/- 2.3 units, P less than .05) after furosemide. Arterial pressure and heart rate did not change. The decrease in central blood volume reflects a shift of the total blood volume from the cardiopulmonary circulation to the periphery, suggesting dilation of the peripheral venous bed. Thus, even in patients undergoing hemodialysis, furosemide acutely decreases left ventricular preload by venous dilation and should therefore prove to be beneficial in acute volume overload.

    The aim of this study was to determine if preemptive use of the NMDA receptor antogonist ketamine decreases postoperative pain in patients undergoing abdominal hystrectomy. A total of 60 patients admitted for total abdominal hysterectomy were included in this study after the approval of the ethic committee, and the patients were randomly classified into three groups. After standart general anaesthesia, before or after incision patients received bolus saline or ketamine. Group S received only saline while Group Kpre received ketamine 0.4 mg/kg before incision and saline after incision, and Group Kpost received saline before incision and 0.4 mg/kg ketamine after incision. Postoperatif analgesia was maintained with i.v. PCA morphine. Pain scores were assessed with Vizüal Analog Scale (VAS), Verbal Rating Scale (VRS) at 1., 2, 3., 4., 8., 12. ve 24. hours postoperatively. First analgesic requirement time, morphine consumption and side effects were recorded. There were no significant differences between groups with respect to VAS / VRS scores, the time for first analgesic dose, and morphine consumption ( p>0.05). Patients in Group S had significantly lower sedation scores than either of the ketamine treated groups ( pketamin had no preemptive analgesic effect in patients undergoing abdominal hysterectomy, but further investigation is needed for different operation types and dose regimens.

    Although red blood cells(RBCs) transfusion is sometimes associated with adverse reactions,anemia could also lead to increased morbidity and mortality in highrisk patients. For these reasons,the definition of perioperative strategies that aims to detect and treat preoperative anemia,prevent excessive blood loss,and define "optimal" transfusion algorithms is crucial. Although the treatment with preoperative iron and erythropoietin has been recommended in some specific conditions,several controversies exist regarding the benefit-to-risk balance associated with these treatments. Further studies are needed to better define the indications,dosage,and route of administration for preoperative iron with or without erythropoietin supplementation. Although restrictive transfusion strategies in patients undergoing cardiac surgery have been shown to effectively reduce the incidence and the amount of RBCs transfusion without increase in side effects,some high-risk patients(e.g.,symptomatic acute coronary syndrome) could benefit from higher hemoglobin concentrations. Despite all efforts made last decade,a significant amount of work remains to be done to improve hemoglobin optimization and transfusion strategies in patients undergoing cardiac surgery.

    Approximately 300 children, from 0 to 18 years old, are diagnosed with cancer in Sweden every year. Of these children, 80-90 of them undergo radiotherapy treatment for their cancer. Although radiotherapy is an encounter with advanced technology, few studies have investigated the child's and the parent's view of the procedure. As part of an ongoing multicenter study aimed to improve patient preparation and the care environment in pediatric radiotherapy, this article reports the findings from interviews with parents at baseline. The aim of the present study was twofold: to describe parents' experience when their child undergoes radiotherapy treatment, and to report parents' suggestions for improvements during radiotherapy for their children. Sixteen mothers and sixteen fathers of children between 2-16 years old with various cancer diagnoses were interviewed. Data were analyzed using content analysis. The findings showed that cancer and treatment turns people's lives upside down, affecting the entire family. Further, the parents experience the child's suffering and must cope with intense feelings. Radiotherapy treatment includes preparation by skilled and empathetic staff. The parents gradually find that they can deal with the process; and lastly, parents have suggestions for improvements during the radiotherapy treatment. An overarching theme emerged: that despair gradually turns to a sense of security, with a sustained focus on and close interaction with the child. In conclusion, an extreme burden was experienced around the start of radiotherapy, though parents gradually coped with the process.

    The aim of this study was to evaluate knowledge of electromyography (EMG) in patients undergoing the procedure. In one year, 1,586 consecutive patients (mean age 56 years; 58.8% women) were admitted to two EMG labs to undergo EMG for the first time. The patients found to be "informed" about the how an EMG examination is performed and about the purpose of EMG numbered 448 (28.2%), while those found to be "informed" only about the manner of its execution or only about its purpose numbered 161 (10.2%) and 151 (9.5%), respectively. The remaining 826 (52.1%) patients had either no information, or the information they had was very poor or incorrect (this was particularly true if they had been consulting websites). Being "informed" was associated with level of education (high), type of referring physician (specialist) and with an appropriate referral diagnosis specified in the EMG request. The quality of patient information on EMG was found to be very poor and could be improved. Physicians referring patients for EMG examinations, especially general practitioners, should assume primary responsibility for patient education and counseling in this field.

    To evaluate the accuracy of dual-energy CT angiography (DE-CTA) maximum intensity projections (MIPs) in symptomatic peripheral arterial occlusive disease (PAOD). In 58 patients, DE-CTA of the lower extremities was performed on dual-source CT. In a maximum of 35 arterial segments, severity of the most stenotic lesion was graded (<10%, 10-49% and 50-99% luminal narrowing or occlusion) independently by two radiologists, with DSA serving as the reference standard. In DSA, 52.3% of segments were significantly stenosed or occluded. Agreement of DE-CTA MIPs with DSA was good in the aorto-iliac and femoro-popliteal regions ({kappa} = 0.72; {kappa} = 0.66), moderate in the crural region ({kappa} = 0.55), slight in pedal arteries ({kappa} = 0.10) and very good in bypass segments ({kappa} = 0.81). Accuracy was 88%, 78%, 74%, 55% and 82% for the respective territories and moderate (75%) overall, with good sensitivity (84%) and moderate specificity (67%). Sensitivity and specificity was 82% and 76% in claudicants and 84% and 61% in patients with critical limb ischaemia. While correlating well with DSA above the knee, accuracy of DE-CTA MIPs appeared to be moderate in the calf and largely insufficient in calcified pedal arteries, especially in patients with critical limb ischaemia.

    Full Text Available Background. We investigated serum testosterone and insulin-like growth factor 1 (IGF-1 levels’ associations with muscle fibre size and resistance training in male dialysis patients. Methods. Male patients were included in a 16-week control period followed by 16 weeks of resistance training thrice weekly. Blood samples were obtained to analyse testosterone, luteinizing hormone (LH, IGF-1, and IGF-binding protein 3. Muscle fibres’ size was analysed in biopsies from m. vastus lateralis. Results. The patients’ testosterone levels were within the normal range at baseline (n=20 (19.5 (8.2–52.1 nmol/L versus 17.6 (16.1–18.0, resp. whereas LH levels were higher (13.0 (5.5–82.8 U/L versus 4.3 (3.3–4.6, P<0.001, resp.. IGF-1 and IGF-binding protein 3 levels were higher in the patients compared with reference values (203 (59–590 ng/mL versus 151 (128–276, P=0.014, and 5045 (3370–9370 ng/mL versus 3244 (3020–3983, P<0.001, resp.. All hormone levels and muscle fibre size (n=12 remained stable throughout the study. Age-adjusted IGF-1 was associated with type 1 and 2 fibre sizes (P<0.05. Conclusion. Patients’ total testosterone values were normal due to markedly increased LH values, which suggest a compensated primary insufficiency of the testosterone producing Leydig cell. Even though testosterone values were normal, resistance training was not associated with muscle hypertrophy. This trial is registered with ISRCTN72099857.

    Full Text Available Haemodynamic monitoring during exercise testing is seldom used during cardiac rehabilitation. The aim was to evaluate haemodynamic changes using the cardiac impedance method during exercise testing in patients after percutaneous coronary interventions and coronary artery bypass grafting during cardiac rehabilitation. Thirty (25 M; 5 F patients were included in the programme. The group was divided according to ejection fraction (EF: low – below 50% normal – equal to or above 50%. The exercise test was performed simultaneously with a four-electrode impedance cardiogram before and after rehabilitation. ECG, blood pressure, thoracic impedance, first derivative dz/dt, stroke volume (SV and cardiac output were recorded. Contractility index (Heather index – HI and vascular peripheral resistance were calculated. The pattern of haemodynamic changes was normal in 24 patients. The deflection poin
