Background
The genotyping of Mycobacterium tuberculosis strains is important to have unique insights into the dissemination dynamics and evolutionary genetics of this pathogen and for TB control as it allows the detection of suspected outbreaks and the tracing of transmission chains.Objective
To characterize M. tuberculois isolates collected from newly diagnosed pulmonary TB patients in Addis AbabaMethods
One hundred and ninety two sputum samples were cultured on Löwenstein-Jensen (LJ) slants and isolates were heat killed for molecular genotyping. The isolates were characterized using spoligotyping and were compared with the International SpoIDB4 database.Result
T genotype constitutes the most predominant in our study (95, 49.5%) followed by the CAS genotype (42, 21.9%). Other genotypes found were Haarlem (H) (24, 12.5%), the LAM (3, 1.5%), the Beijing genotype (1, 0.5%); four (2.1%) isolates were designated as Unknown.Conclusion
All the isolates belong to the modern lineage and there is high clustering in the genotype of isolates which indicated the presence of recent TB transmission. Therefore, the Tuberculosis Control Programme needs to do more in advocating and strengthening the health system for early detection and treatment of active TB cases as delay in treatment is the key factor in disease transmission. 相似文献2.

Purpose
We sought to evaluate the clinical usefulness of decision making by a multidisciplinary heart team for identifying potential candidates for transcatheter aortic valve implantation (TAVI) in patients with symptomatic severe aortic stenosis.Materials and Methods
The multidisciplinary team consisted of two interventional cardiologists, two cardiovascular surgeons, one cardiac imaging specialist, and two cardiac anesthesiologists.Results
Out of 60 patients who were screened as potential TAVI candidates, 31 patients were initially recommended as appropriate for TAVI, and 20 of these 31 eventually underwent TAVI. Twenty-two patients underwent surgical aortic valve replacement (AVR), and 17 patients received only medical treatment. Patients who underwent TAVI and medical therapy were older than those who underwent surgical AVR (p<0.001). The logistic Euroscore was significantly highest in the TAVI group and lowest in the surgical AVR group (p=0.012). Most patients in the TAVI group (90%) and the surgical AVR group (91%) had severe cardiac symptoms, but only 47% in the medical therapy group had severe symptoms. The cumulative percentages of survival without re-hospitalization or all-cause death at 6 months for the surgical AVR, TAVI, and medical therapy groups were 84%, 75%, and 28%, respectively (p=0.007, by log-rank).Conclusion
TAVI was recommended in half of the potential candidates following a multidisciplinary team approach and was eventually performed in one-third of these patients. One-third of the patients who were initially considered potential candidates received surgical AVR with favorable clinical outcomes. 相似文献3.

INTRODUCTION:
In obsessive-compulsive disorder, early treatment discontinuation can hamper the effectiveness of first-line treatments.OBJECTIVE:
This study aimed to investigate the clinical correlates of early treatment discontinuation among obsessive-compulsive disorder patients.METHODS:
A group of patients who stopped taking selective serotonin reuptake inhibitors (SSRIs) or stopped participating in cognitive behavioral therapy before completion of the first twelve weeks (total n = 41; n = 16 for cognitive behavioral therapy and n = 25 for SSRIs) were compared with a paired sample of compliant patients (n = 41). Demographic and clinical characteristics were obtained at baseline using structured clinical interviews. Chi-square and Mann-Whitney tests were used when indicated. Variables presenting a p value <0.15 for the difference between groups were selected for inclusion in a logistic regression analysis that used an interaction model with treatment dropout as the response variable.RESULTS:
Agoraphobia was only present in one (2.4%) patient who completed the twelve-week therapy, whereas it was present in six (15.0%) patients who dropped out (p = 0.044). Social phobia was present in eight (19.5%) patients who completed the twelve-week therapy and eighteen (45%) patients who dropped out (p = 0.014). Generalized anxiety disorder was present in eight (19.5%) patients who completed the twelve-week therapy and twenty (50%) dropouts (p = 0.004), and somatization disorder was not present in any of the patients who completed the twelve-week therapy; however, it was present in six (15%) dropouts (p = 0.010). According to the logistic regression model, treatment modality (p = 0.05), agoraphobia, the Brown Assessment of Beliefs Scale scores (p = 0.03) and the Beck Anxiety Inventory (p = 0.02) scores were significantly associated with the probability of treatment discontinuation irrespective of interactions with other variables.DISCUSSION AND CONCLUSION:
Early treatment discontinuation is a common phenomenon in obsessive-compulsive disorder patients from our therapeutic setting. Psychiatric comorbidities were associated with discontinuation rates of specific treatments. Future studies might use this information to improve management for increased compliance and treatment effectiveness. 相似文献4.
Purpose
The purposes of this study were to evaluate specific dysphagia patterns and to identify the factors affecting dysphagia, especially aspiration, following treatment of head and neck cancer.Materials and Methods
A retrospective analysis of 57 patients was performed. Dysphagia was evaluated using a modified barium swallow (MBS) test. The MBS results were rated on the 8-point penetration-aspiration scale (PAS) and swallowing performance status (SPS) score.Results
Reduced base of the tongue (BOT) retraction (64.9%), reduced laryngeal elevation (57.9%), and cricopharyngeus (CP) dysfunction (47.4%) were found. Reduced BOT retraction was correlated with clinical stage (p=0.011) and treatment modality (p=0.001). Aspiration in 42.1% and penetration in 33.3% of patients were observed. Twenty-four patients had PAS values over 6, implying aspiration. Forty-one patients had a SPS score of more than 3, 25 patients had a score greater than 5, and 13 patients had a SPS score of more than 7. Aspiration was found more often in patients with penetration (p=0.002) and in older patients (p=0.026). In older patients, abnormal swallowing caused aspiration even in those with a SPS score of more than 3, irrespective of stage or treatment, contrary to younger patients. Tube feeders (n=20) exhibited older age (65.0%), dysphagia/aspiration related structures (DARS) primaries (75.0%), higher stage disease (66.7%), and a history of radiotherapy (68.8%).Conclusion
Reduced BOT retraction was the most common dysphagia pattern and was correlated with clinical stage and treatment regimens including radiotherapy. Aspiration was more frequent in patients who had penetration and in older patients. In contrast to younger patients, older patients showed greater risk of aspiration even with a single abnormal swallowing irrespective of stage or treatment. 相似文献5.

Purpose
Tuberculosis (TB) is a major infectious disease and is responsible for two million deaths annually. For the identification and quantitation of Mycobacterium tuberculosis (M. tuberculosis), a causative agent of TB, a sandwich enzyme-linked immunosorbent assay (ELISA) against the MPT64 protein of M. tuberculosis, an antigen marker of the M. tuberculosis complex, was developed.Materials and Methods
The MPT64 protein was expressed, and anti-MPT64 monoclonal antibodies were prepared. A sandwich ELISA was established using recombinant MPT64 protein and anti-MPT64 monoclonal antibodies. The sandwich MPT64 ELISA was evaluated using reference and clinical mycobacterial strains.Results
The sandwich MPT64 ELISA detected MPT64 protein from 2.1 ng/mL to 250 ng/mL (equivalent to 1.7×104 CFU/mL and 2.0×106 CFU/mL). All 389 clinical M. tuberculosis isolates tested positive in the sandwich MPT64 ELISA (sensitivity, 100%), and the assay showed no cross reactivity to any tested nontuberculous mycobacterial strain (specificity, 100%).Conclusion
The sandwich MPT64 ELISA is a highly sensitive and quantitative test for MPT64 protein, which can identify M. tuberculosis. 相似文献6.

Purpose
To compare the outcomes of thoracic endovascular aortic repair (TEVAR) with those of open repair for descending thoracic aortic aneurysms (DTAA).Materials and Methods
We compared the outcomes of 114 patients with DTAA and proximal landing zones 3 or 4 after TEVAR to those of 53 patients after conventional open repairs. Thirty-day and late mortality were the primary endpoints, and early morbidities, aneurysm-related death, and re-intervention were the secondary endpoints.Results
The TEVAR group was older and had more incidences of dissecting aneurysm. The mean follow-up was 36±26 months (follow-up rate, 97.8%). The 30-day mortality in the TEVAR and open repair groups were 3.5% and 9.4% (p=0.11). Perioperative stroke and paraplegia incidences were similar between the groups [5.3% vs. 7.5% (p=0.56) and 7.5% vs. 3.5% (p=0.26), respectively]. Respiratory failure occurred more in the open repair group (1.8% vs. 26.4%, p<0.01). The incidence of acute kidney injury requiring dialysis was higher in the open repair group (1.8% vs. 9.4%, p<0.01). The cumulative survival rate was higher in the TEVAR group at 2 to 5 years (79.6% vs. 58.3%, p=0.03). The free from re-intervention was lower in the TEVAR group (65.3% vs. 100%, p=0.02), and the free from aneurysm-related death in the TEVAR and open repair groups were 88.5% and 86.1% (p=0.45).Conclusion
TEVAR is safe and effective for treating DTAAs with improved perioperative and long-term outcomes compared with open repair. 相似文献7.
Background
We determined the genetic diversity of mycobacteria isolated from tuberculosis patients in Mbarara Uganda, using region of difference (RD) analysis and spacer oligonucleotide typing (spoligotyping).Methods
Sputum samples were cultured on Lowenstein Jensen media. The isolates were characterized using RD analysis and spoligotyping.Results
The majority (92.8%) of the patients were new cases, 60% were males and 44% were HIV positive with a mean age of 33.7 years. All the 125 isolates were identified as M.tuberculosis sensu stricto. Most (92.8%) of the isolates were modern strains. Spoligotyping revealed 79 spoligotype patterns, with an overall diversity of 63.2%. Sixty (48%) isolates formed 16 clusters each consisting of 2–15 isolates. Mst (59.2 %) of the isolates were Uganda genotype strains. The major shared spoligotypes in our sample were SIT 135 (T2-Uganda) with 12 isolates and SIT 128 (T2) with 5 isolates. Sixty nine (87%) patterns had not yet been defined in the SpolDB4.0.database.Conclusion
The TB epidemic in Mbarara is caused mainly by modern M.tuberculosis strains of the Uganda genotype. The wide diversity of strains may indicate that the majority of the TB cases are reactivation rather than re-infection. However this needs to be ascertained with more discriminative finger printing techniques. 相似文献8.

Purpose
Methicillin-resistant Staphylococcus aureus (MRSA) is recognized as an important cause of not only healthcare-associated pneumonia (HCAP) but also community-acquired pneumonia (CAP). We determined the impact of MRSA on differences in clinical characteristics, courses, and outcomes between CAP and HCAP.Materials and Methods
We conducted a retrospective observational study on 78 adult patients admitted with MRSA pneumonia at a university-affiliated tertiary hospital between January 2008 and December 2011. We compared baseline characteristics, chest radiographs, treatment outcomes, and drug resistance patterns between the CAP and HCAP groups.Results
Of the 78 patients with MRSA pneumonia, 57 (73.1%) were HCAP and 21 (26.9%) were CAP. MRSA infection history in the previous year (29.8% vs. 14.3%, p=0.244) tended to be more common in HCAP than in CAP. Despite similar Pneumonia Severity Index scores (151 in CAP vs. 142 in HCAP), intubation rates (38.1% vs. 17.5%; p=0.072) and intensive care unit admission (42.9% vs. 22.8%; p=0.095) tended to be higher in the CAP group, while 28-day mortality was higher in the HCAP group (14.3% vs. 26.3%; p=0.368), although without statistical significance. All patients showed sensitivity to vancomycin and linezolid; meanwhile, HCAP patients showed greater resistance to gentamicin than CAP patients (58.3% vs. 16.6%; p=0.037). The median total hospital charges were 6899 American dollars for CAP and 5715 American dollars for HCAP (p=0.161).Conclusion
MRSA pneumonia showed significantly differences in baseline characteristics, chest radiographs, treatment outcomes, and medical expenses between HCAP and CAP groups. 相似文献9.

Purpose
Studies have shown that diabetes mellitus (DM) is a risk factor for cardiovascular disease, including atrial fibrillation (AF); however, the clinical characteristics and prognostic impact of DM in patients with nonvalvular AF have not been well understood in China.Materials and Methods
Included were 1644 consecutive patients with nonvalvular AF. Endpoints included all-cause mortality, cardiovascular mortality, stroke, major bleeding, and combined endpoint events (CEE) during a 1-year follow-up.Results
The prevalence of DM was 16.8% in nonvalvular AF patients. Compared with non-diabetic AF patients, diabetic AF patients were older and tended to coexist with other cardiovascular diseases. Most patients with DM (93.5%) were eligible for anticoagulation, as determined by CHADS2 scores. However, only 11.2% of patients received anticoagulation. During a 1-year follow-up, the all-cause mortality and CEE rate in the DM group were significantly higher than those of the non-DM group, while the incidence of stroke was comparable. After multivariate adjustments, DM was still an independent risk factor for 1-year all-cause mortality [hazard ratio (HR)=1.558; 95% confidence interval (CI) 1.126-2.156; p=0.007], cardiovascular mortality (HR=1.615; 95% CI 1.052-2.479; p=0.028), and CEE (HR=1.523; 95% CI 1.098-2.112; p=0.012), yet not for stroke (HR=1.119; 95% CI 0.724-1.728; p=0.614).Conclusion
DM is a common morbidity coexisting with nonvalvular AF and is associated with an increased risk of 1-year all-cause mortality, cardiovascular mortality, and CEE. However, no increased risk of stroke was found during a 1-year follow-up in patients with AF and DM. 相似文献10.

Purpose
Coronary artery bypass grafting (CABG) is the optimal treatment option for left main coronary artery disease (LMCAD). However, LMCAD remains a constant topic of discussion between cardiac surgeons and interventional cardiologists. The aim of this study was to assess the efficacy of LMCAD treatments by comparing the mid-term outcomes of CABG and percutaneous coronary intervention (PCI) using bare metal stents or drug-eluting stents (DESs).Materials and Methods
The study population was comprised of 199 consecutive patients admitted with unprotected LMCAD. All of the patients were assigned to PCI (88 patients) or CABG (111 patients). The primary clinical end point indicated death, stroke of acute coronary syndrome (ACS).Results
Patients assigned to PCI were at higher operative risk than patients scheduled for CABG (6.49±4.09 vs. 4.81±2.67, p=0.0032). Comparison of the group that received DESs with the CABG group did not reveal any differences in major adverse cardio-cerebral events (MACCE) occurrence (21% vs. 16%, p=NS). Patients in the CABG and PCI groups died with similar frequency (11% vs. 16%, p=NS). The mortality rate in the CABG group was higher than among those treated with DES (11% vs. 3%, p=0.049). The rate of ACS was higher in the PCI group than in the CABG group (13% vs. 4%, p=0.016).Conclusion
Despite the fact that patients treated with PCI were at higher operative risk, PCI with DES was shown to be comparable to CABG in terms of mortality, stroke and ACS. However, the frequency of repeat revascularizations remains a constant concern with PCI. 相似文献11.

Purpose
To analyze overall survival (OS), prostate cancer (PCa)-specific survival (PCaSS), and non-PCaSS according to the Charlson Comorbidity Index (CCI) after radical prostatectomy (RP) for PCa.Materials and Methods
Data from 336 patients who had RP for PCa between 1992 and 2005 were analyzed. Data included age, preoperative prostate-specific antigen (PSA), prostate volume, clinical stage, and pathologic stage. Pre-existing comorbidities were evaluated by the CCI, and patients were classified into two CCI score categories (0, ≥1).Results
The mean age of patients was 64.31±6.12 years. The median PSA value (interquartile range, IQR) was 11.30 (7.35 and 21.02) ng/mL with a median follow-up period (IQR) of 96.0 (85.0 and 121.0) months. The mean CCI was 0.28 (0-4). Five-year OS, PCaSS, and non-PCaSS were 91.7%, 96.3%, and 95.2%, respectively. Ten-year OS, PCaSS, and non-PCaSS were 81.9%, 92.1%, and 88.9%, respectively. The CCI had a significant influence on OS (p=0.022) and non-PCaSS (p=0.008), but not on PCaSS (p=0.681), by log-rank test. In multivariate Cox regression analysis, OS was independently associated with the CCI [hazard ratio (HR)=1.907, p=0.025] and Gleason score (HR=2.656, p<0.001). PCaSS was independently associated with pathologic N stage (HR=2.857, p=0.031), pathologic T stage (HR=3.775, p=0.041), and Gleason score (HR=4.308, p=0.001). Non-PCaSS had a significant association only with the CCI (HR=2.540, p=0.009).Conclusion
The CCI was independently associated with both OS and non-PCaSS after RP, but the CCI had no impact on PCaSS. The comorbidities of a patient should be considered before selecting RP as a curative modality for PCa. 相似文献12.

Purpose
The aim of this study was to analyze the results of children treated with hemodialysis (HD) at Severance Hospital over 35 years in terms of incidence, etiologies, characteristics, complications, and clinical outcomes.Materials and Methods
We analyzed 46 children admitted to Severance Hospital who had undergone HD between January 1979 and December 2013.Results
The main etiologies of the 23 end-stage renal disease (ESRD) patients who had received HD were chronic glomerulonephritis (7 patients, 30.4%) and congenital anomalies of the kidney and urinary tract (7 patients, 30.4%), whereas the etiology of the 23 acute kidney injury (AKI) patients was hemolytic uremic syndrome (6 patients, 26.1%). Compared with ESRD patients, hemocatheter placement in the femoral vein was preferred over the subclavian or internal jugular vein in the AKI patients (p=0.012). The most common complication was catheter related complication (10 patients, 21.7%). The site of hemocatheter insertion was not related to the frequency of oozing. Placing the hemocatheter in the femoral vein resulted in significantly more events of catheter obstruction than insertion in the internal jugular vein or the subclavian vein (p=0.001). Disequilibrium syndrome occurred more frequently in older patients (p=0.004), as well as patients with a greater body weight (p=0.008) and a higher systolic and diastolic blood pressure before HD (systolic: p=0.021; diastolic: p=0.040).Conclusion
Based on the 35 years of experience in our center, HD can be sufficiently and safely carried out even in children without significant complications. 相似文献13.
Purpose
Healthcare-associated pneumonia (HCAP) has been proposed as a new category of pneumonia. However, epidemiological studies for HCAP in South Korea are limited. This study aimed to reveal the differences between HCAP and community-acquired pneumonia (CAP), especially in elderly patients, in university-affiliated hospital in South Korea.Materials and Methods
We conducted a retrospective observational study of patients with HCAP and CAP (older than 60 years old) who were hospitalized between January 2007 and December 2008. We compared the baseline characteristics, comorbidities, severity, pathogen distribution, antibiotics, and clinical outcomes.Results
A total of 210 patients were evaluated, including 35 patients with HCAP (17%) and 175 with CAP (83%). The most common causative organism was Streptococcus pneumoniae in CAP (33.3%), whereas, Staphylococcus aureus was most common pathogen in HCAP (40.0%). Initial inappropriate antibiotics (6.3% vs. 22.9%; p < 0.005) and initial treatment failure (15.4% vs. 31.4%; p = 0.018) were more frequent in HCAP than CAP. However, mortality (11.4% vs. 5.7%; p = 0.369) was not different between the two groups.Conclusion
The present study provides additional evidence that HCAP should be distinguished from CAP, even in elderly patients, in South Korea. Physicians should consider S. aureus and MDR pathogens in selecting initial empirical antibiotics of HCAP in South Korea. 相似文献14.
Purpose
Transplant recipients in Asia appear to be at a higher risk for developing colorectal cancer (CRC). This study was performed to identify the clinicopathological features and oncologic outcomes of CRC in post-renal transplants in Korea.Materials and Methods
We retrospectively reviewed the records of 17 patients with CRC out of 2,630 recipients who underwent renal transplantation between 1994 and 2007. These patients (transplant group) were compared with general CRC patients (n=170, control group) matched, based on the closest date of surgery to the transplant group.Results
During 29.7 months of the median follow-up period, the recurrent and survival rates from recurrence were worse in the transplant group than in the control group (35.2% versus 15.2%; p=0.048 and p=0.025). The 2-year patient survival rate of the transplant group was significantly worse than the control group in advanced cancer (stages III-IV; 45.7% versus 71.6%; p=0.023). In early cancer (stages 0-I), there was no significant difference in 5-year patient survival rate between the two groups (100% versus 92.6%, respectively; p=0.406).Conclusion
In spite of a poor prognosis of advanced CRC in the transplant group, the early stage CRC of the transplant group showed a comparable oncologic outcome compared with the control group. Regular screening and early detection of CRC are essential in the post-transplant setting. 相似文献15.

Purpose
The modified Glasgow Prognostic Score (mGPS) consisting of serum C-reactive protein and albumin levels, shows significant prognostic value in several types of tumors. We evaluated the prognostic significance of mGPS in 285 patients with diffuse large B cell lymphoma (DLBCL), retrospectively.Materials and Methods
According to mGPS classification, 204 patients (71.5%) had an mGPS of 0, 57 (20%) had an mGPS of 1, and 24 (8.5%) had an mGPS of 2.Results
Our study found that high mGPS were associated with poor prognostic factors including older age, extranodal involvement, advanced disease stage, unfavorable International Prognostic Index scores, and the presence of B symptoms. The complete response (CR) rate after 3 cycles of R-CHOP chemotherapy was higher in patients with mGPS of 0 (53.8%) compared to those with mGPS of 1 (33.3%) or 2 (25.0%) (p=0.001). Patients with mGPS of 0 had significantly better overall survival (OS) than those with mGPS=1 and those with mGPS=2 (p=0.036). Multivariate analyses revealed that the GPS score was a prognostic factor for the CR rate of 3 cycle R-CHOP therapy (p=0.044) as well as OS (p=0.037).Conclusion
mGPS can be considered a potential prognostic factor that may predict early responses to R-CHOP therapy in DLBCL patients. 相似文献16.

PURPOSE:
The aim of this study was to evaluate the effect of dexmedetomidine on shivering during spinal anesthesia.METHODS:
Sixty patients (American Society of Anesthesiologists physical status I or II, aged 18-50 years), scheduled for elective minor surgical operations under spinal anesthesia with hyperbaric bupivacaine, were enrolled. They were administered saline (group C, n = 30) or dexmedetomidine (group D, n = 30). Motor block was assessed using a Modified Bromage Scale. The presence of shivering was assessed by a blinded observer after the completion of subarachnoid drug injection.RESULTS:
Hypothermia was observed in 21 patients (70%) in group D and in 20 patients (66.7%) in group C (p = 0.781). Three patients (10%) in group D and 17 patients (56.7%) in group C experienced shivering (p = 0.001). The intensity of shivering was lower in group D than in group C (p = 0.001). Time from baseline to onset of shivering was 10 (5-15) min in group D and 15 (5-45) min in group C (p = 0.207).CONCLUSION:
Dexmedetomidine infusion in the perioperative period significantly reduced shivering associated with spinal anesthesia during minor surgical procedures without any major adverse effect during the perioperative period. Therefore, we conclude that dexmedetomidine infusion is an effective drug for preventing shivering and providing sedation in patients during spinal anesthesia. 相似文献17.

OBJECTIVE:
Hyperhidrosis is a common disease, and thoracoscopic sympathectomy improves its symptoms in up to 95% of cases. Unfortunately, after surgery, plantar hyperhidrosis may remain in 50% of patients, and compensatory sweating may be observed in 70%. This clinical scenario remains a challenge. Our objective was to evaluate the effectiveness of oxybutynin in the treatment of persistent plantar hyperhidrosis and compensatory sweating and its effects on quality of life in women after thoracoscopic sympathectomy.METHOD:
We conducted a prospective, randomized study to compare the effects of oxybutynin at 10 mg daily and placebo in women with persistent plantar hyperhidrosis. The assessment was performed using a quality-of-life questionnaire for hyperhidrosis and sweating measurement with a device for quantifying transepidermal water loss. Clinicaltrials.gov: NCT01328015.RESULTS:
Sixteen patients were included in each group (placebo and oxybutynin). There were no significant differences between the groups prior to treatment. After oxybutynin treatment, there was a decrease in symptoms and clinical improvement based on the quality-of-life questionnaire (before treatment, 40.4 vs. after treatment, 17.5; p = 0.001). The placebo group showed modest improvement (p = 0.09). The outcomes of the transepidermal water loss measurements in the placebo group showed no differences (p = 0.95), whereas the oxybutynin group revealed a significant decrease (p = 0.001). The most common side effect was dry mouth (100% in the oxybutynin group vs. 43.8% in the placebo group; p = 0.001).CONCLUSION:
Oxybutynin was effective in the treatment of persistent plantar hyperhidrosis, resulting in a better quality of life in women who had undergone thoracoscopic sympathectomy. 相似文献18.

Purpose
The identification of sick sinus syndrome (SSS) in patients with atrial flutter (AFL) is difficult before the termination of AFL. This study investigated the patient characteristics used in predicting a high risk of SSS after AFL ablation.Materials and Methods
Out of 339 consecutive patients who had undergone radiofrequency ablation for AFL from 1991 to 2012, 27 (8%) had SSS (SSS group). We compared the clinical characteristics of patients with and without SSS (n=312, no-SSS group).Results
The SSS group was more likely to have a lower body mass index (SSS: 22.5±3.2; no-SSS: 24.0±3.0 kg/m2; p=0.02), a history of atrial septal defects (ASD; SSS: 19%; no-SSS: 6%; p=0.01), a history of coronary artery bypass graft surgery (CABG; SSS: 11%; no-SSS: 2%; p=0.002), and a longer flutter cycle length (CL; SSS: 262.3±39.2; no-SSS: 243.0±40; p=0.02) than the no-SSS group. In multivariate analysis, a history of ASD [odds ratio (OR) 3.7, 95% confidence interval (CI) 1.2-11.4, p=0.02] and CABG (7.1, 95% CI 1.5-32.8, p=0.01) as well as longer flutter CL (1.1, 95% CI 1.0-1.2, p=0.04) were independent risk factors for SSS.Conclusion
A history of ASD and CABG as well as longer flutter CL increased the risk of SSS after AFL ablation. While half of the patients with SSS after AFL ablation experienced transient SSS, heart failure was associated with irreversible SSS. 相似文献19.

Purpose
Recently, mitochondrial DNA 4977bp deletion (mtDNA4977-mut), a somatic mutation related to oxidative stress, has been shown to be associated with atrial fibrillation (AF). We hypothesized that patient age, as well as electroanatomical characteristics of fibrillating left atrial (LA), vary depending on the presence of mtDNA4977-mut in peripheral blood among patients with non-valvular AF.Materials and Methods
Analyzing clinical and electroanatomical characteristics, we investigated the presence of the mtDNA4977-mut in peripheral blood of 212 patients (51.1±13.2 years old, 83.5% male) undergoing catheter ablation for non-valvular AF, as well as 212 age-matched control subjects.Results
The overall frequency of peripheral blood mtDNA4977-mut in patients with AF and controls was not significantly different (24.5% vs. 19.3%, p=0.197). When the AF patient group was stratified according to age, mtDNA4977-mut was more common (47.4% vs. 20.0%, p=0.019) in AF patients older than 65 years than their age-matched controls. Among AF patients, those with mtDNA4977-mut were older (58.1±11.9 years old vs. 48.8±11.9 years old, p<0.001). AF patients positive for the mtDNA mutation had greater LA dimension (p=0.014), higher mitral inflow peak velocity (E)/diastolic mitral annular velocity (Em) ratio (p<0.001), as well as lower endocardial voltage (p=0.035), and slower conduction velocity (p=0.048) in the posterior LA than those without the mutation. In multivariate analysis, E/Em ratio was found to be significantly associated with the presence of mtDNA4977-mut in peripheral blood.Conclusion
mtDNA4977-mut, an age-related somatic mutation detected in the peripheral blood, is associated with advanced age and electro-anatomical remodeling of the atrium in non-valvular AF. 相似文献20.
