A 68-year-old woman with a left renal artery aneurysm underwent successful endovascular repair with the use of a commercial type self-expanding stent-graft. Complete aneurysm exclusion was achieved after stent-graft expansion. A side branch vessel was occluded after stent-placement, resulting in a small upper lobe renal perfusion defect. There were no other complications. The aneurysm remained excluded and its greatest diameter has been reduced from 2.6 cm to 1.95 cm, 10 months after treatment. Renal function remained normal. 相似文献

We assessed validity and reliability of the new 20m square shuttle run test (SST) for predicting maximal oxygen uptake (V O(2max)) and compared it with its predecessor, the 20m Multistage Shuttle Run Test (MST). In a repeated-measures randomised-block design, 74 healthy adult males performed the SST, the MST and a treadmill test (TT). To assess reliability, 40 of the total 74 volunteers were randomly-selected to perform the SST and MST twice. Unlike the SST (p>0.05), mean predicted V O(2max)(V predO(2max)) from the MST was significantly increased from that measured during the TT (p<0.05). The V predO(2max) from SST and MST correlated with TT V O(2max) at r=0.95 (p<0.001) and r=0.63 (p<0.001), respectively. Prediction error of SST was -0.3+/-3.3mlkg(-1)min(-1) with a coefficient of variation of +/-3.5%, while the equivalent values for MST were 4.2+/-7.3mlkg(-1)min(-1) and +/-7.4%. Mean test-retest V predO(2max) did not differ for both SST and MST (p>0.05), while the corresponding test-retest correlation coefficients were r=0.85 (p<0.001) and r=0.72 (p<0.001). Reliability errors in 95% limits of agreement were 0.3+/-4.8 and 0.6+/-6.8mlkg(-1)min(-1) while coefficients of variation were +/-5.2% and +/-6.8% for the SST and MST, respectively. It is concluded that SST is a more valid proxy than MST for predicting laboratory V O(2max) based on the current procedures, while both tests are sufficiently reliable in healthy male adults. 相似文献

BACKGROUND: In the present study we investigated the effect of a 6-month aerobic exercise programme on the morphology of the gastrocnemius muscle of end-stage renal disease (ESRD) patients. METHODS: Twenty-four ESRD patients volunteered to participate in the training programme and underwent muscle biopsy before training. Eighteen patients completed the training programme of whom nine agreed to a post-training biopsy (one woman and eight men, mean age 56 +/- 15 years). Data are presented for the nine subjects who were biopsied before (PRE) and after training (POST) and separately for the 15 subjects for whom we only have a biopsy before training (cross-sectional group). RESULTS: There were no significant differences (P > 0.05) in fibre type distribution or myosin heavy chain (MyHC) expression between the cross-sectional and PRE/POST groups. The mean cross-section fibre area after training (POST) increased by 46% compared with the PRE training status (P < 0.01). The proportion of atrophic fibres decreased significantly after training in type I, IIa and IIx fibre populations (from 51 to 15%, 58 to 21% and 62 to 32%, respectively). Significant differences were also found in capillary contact per fibre (CC/F), with the muscle having 24% (P < 0.05) more CC/F compared with the PRE training status. No significant differences in cytochrome c oxidase concentration were found between the groups. CONCLUSIONS: In conclusion, exercise appeared to be beneficial in renal rehabilitation by correcting the fibre atrophy, increasing the cross-section fibre area and improving the capillarization in the skeletal muscle of renal failure patients. 相似文献

Mutations within the low density lipoprotein (LDL)-receptor gene result in familial hypercholesterolemia, an autosomal dominant inherited disease. Clinical homozygous affected subjects die of premature coronary artery disease as early as in early childhood. We identified a girl at the age of five yr with clinical homozygous familial hypercholesterolemia presenting with achilles tendon xanthomas and arcus lipoides. Her total cholesterol reached up to 1050 mg/dL. Molecular characterization of the LDL-receptor gene revealed a homozygous p.W577R mutation. Despite intensive treatment interventions with the combination of diet, statins, colestipol, and LDL-apheresis, the patient developed symptomatic coronary artery disease at the age of 16 yr. Subsequently, orthotopic liver transplantation was performed to cure the defective LDL-receptor gene. Clinical follow-up for almost nine yr post-transplantation revealed excellent liver function, normal liver enzymes, normal LDL-cholesterol, and regression of both tendon xanthomas and symptomatic coronary artery disease. In conclusion, liver transplantation can effectively reduce LDL-cholesterol in a familial hypercholesterolemia recipient with subsequent regression of xanthomas and atherosclerosis. Timing is extremely important in these exceptional cases to exclude the demand for heart transplantation due to severe coronary artery disease. In addition, the identification of the LDL-receptor as etiology of clinical homozygous hypercholesterolemia is a prerequisite once liver transplantation is considered as therapeutic option. 相似文献

IntroductionRegenerative endodontic procedures (REPs) are intended to repair and regenerate part of the pulp-dentin complex. The aim of this study was to systematically appraise the existing evidence on the effectiveness of REPs on mature teeth with pulp necrosis and apical periodontitis.MethodsElectronic database and hand searches were performed on 8 databases of published and unpublished literature from inception to January 3, 2021, for the identification of randomized controlled trials (RCTs) or prospective clinical trials. The related key words included “regenerative,” “pulp revascularization,” “revitalization procedure,” and “necrotic mature teeth.” A random effects meta-analysis was conducted assessing success as the main outcome treatment. Risk of bias was assessed through the Cochrane Risk of Bias 2.0 tool, and the quality of the evidence was assessed with the Grading of Recommendations Assessment, Development and Evaluation approach.ResultsOf the 337 initial hits, 4 RCTs were eligible for inclusion, whereas 3 were included in the quantitative synthesis. Overall, there was no difference in the relative risk for a successful/unsuccessful treatment outcome between REPs or conventional treatment (3 studies, relative risk = 1.03; 95% confidence interval, 0.92–1.15; P = .61; heterogeneity I2 = 0.0%, P = .53; prediction interval = 0.51–2.09). Risk of bias ranged from low to raising some concerns, whereas the quality of the evidence was graded as moderate.ConclusionsBased on moderate-quality evidence, REPs appear as a viable treatment alternative for mature necrotic teeth with periapical lesions at present. Furthermore, well-designed RCTs might also provide confirmatory evidence in this respect while also framing a backbone for standardization of the therapeutic protocol of REPs. 相似文献

Background
TNF-like cytokine 1A provides co-stimulatory signals to activated lymphocytes through binding to death-domain receptor-3. Decoy receptor-3 inhibits death-domain receptor-3 signalling, rendering immunocytes resistant to apoptosis. These functions may be important for the pathogenesis of Crohn's disease.Aims
To study the mucosal and systemic expression of Decoy receptor-3 and TNF-like cytokine 1A in Crohn's disease, in relation to disease activity, localization, and response to treatment.Methods
Soluble Decoy receptor-3 and TNF-like cytokine 1A were measured by ELISA in active or quiescent Crohn's disease. Relative mRNA expression in non-affected and inflamed intestinal mucosa was determined by real-time RT-PCR.Results
We found significant upregulation of Decoy receptor-3 and its ligands TNF-like cytokine 1A and FasL in inflamed intestinal mucosa of Crohn's disease patients. During active disease, Decoy receptor-3 and TNF-like cytokine 1A were detected in the serum in the majority of patients. Intestinal inflammation was strongly associated with these elevations as they were absent during remission and significantly reduced with anti-inflammatory treatment. Regional diversity was observed as Decoy receptor-3 was upregulated in colonic and ileal sites, whereas TNF-like cytokine 1A was preferentially induced in the large bowel mucosa and systemic circulation of patients with colonic involvement.Conclusions
TNF-like cytokine 1A and Decoy receptor-3 are upregulated during active Crohn's disease and may participate in disease pathogenesis and offer novel therapeutic opportunities. 相似文献9.

The purpose of the present study was to investigate the effects of 6 weeks strength vs. ballistic-power (Power) training on shot put throwing performance in novice throwers. Seventeen novice male shot-put throwers were divided into Strength (N = 9) and Power (n = 8) groups. The following measurements were performed before and after the training period: shot put throws, jumping performance (CMJ), Wingate anaerobic performance, 1RM strength, ballistic throws and evaluation of architectural and morphological characteristics of vastus lateralis. Throwing performance increased significantly but similarly after Strength and Power training (7.0-13.5% vs. 6.0-11.5%, respectively). Muscular strength in leg press increased more after Strength than after Power training (43% vs. 21%, respectively), while Power training induced an 8.5% increase in CMJ performance and 9.0 - 25.8% in ballistic throws. Peak power during the Wingate test increased similarly after Strength and Power training. Muscle thickness increased only after Strength training (10%, p < 0.05). Muscle fibre Cross Sectional Area (fCSA) increased in all fibre types after Strength training by 19-26% (p < 0.05), while only type IIx fibres hypertrophied significantly after Power training. Type IIx fibres (%) decreased after Strength but not after Power training. These results suggest that shot put throwing performance can be increased similarly after six weeks of either strength or ballistic power training in novice throwers, but with dissimilar muscular adaptations.
Key points
- Ballistic-power training with 30% of 1RM is equally effective in increasing shot put performance as strength training, in novice throwers, during a short training cycle of six weeks.
- In novice shot putters with relatively low initial muscle strength/mass, short-term strength training might be more important since it can increase both muscle strength and shot put performance.
- The ballistic type of power training resulted in a significant increase of the mass of type IIx muscle fibres and no change in their proportion. Thus, this type of training might be used effectively during the last weeks before competition, when the strength training load is usually reduced, in order to increase muscle power and shot put performance in novice shot putters.
