Abstract: background: transfemoral access is the preferred approach for transcatheter aortic valve implantation. however, some situations, such as the presence of peripheral vascular disease, preclude the use of such access. in these cases, subclavian access is an alternative approach for this procedure. this study aimed at evaluating the brazilian experience using the subclavian approach for transcatheter corevalve? prosthesis implantation. methods: aortic valve area < 1 cm2, aortic valve ring ≥ 20 mm and ≤ 27 mm (26 mm and 29 mm corevalve?), ascending aorta ≤ 43 mm and subclavian artery with a diameter ≥ 6 mm, without significant obstructive lesions, marked tortuosity and excess calcification were requisites for the procedure. the access through the subclavian artery was obtained by surgical dissection and, under direct vision, a subclavian artery puncture was performed. once artery access was obtained, the standard technique was used. results: between january 2008 and april 2012, 8 patients with peripheral vascular disease underwent corevalve? prosthesis implantation through the subclavian artery in 4 institutions. the procedure was successful in all cases with reduction of the mean transvalvular pressure gradient from 46.4 ± 17.5 mmhg to 9.3 ± 3.6 mmhg (p = 0.0018) and improvement of symptoms. at 30 days and after 275 ± 231 days of follow-up, 87.5% and 62.5% of the patients, respectively, were free from major adverse events (death, myocardial infarction, stroke and urgent cardiac surgery). conclusions: in the brazilian experience, the subclavian access was a safe and effective alternative for transcatheter corevalve? implantation.

Abstract: the objective of this study was to investigate the causes of the repeat breeder syndrome comparing clinical signs and postmortem findings in beef cows. the identification of factors affecting the reproductive tract can support decisions as to whether treatment of repeat breeder cows is justifiable than culling. since all animals were submitted to clinical examination before being slaughtered, this study has a differential approach when compared with others, where genital tracts from abattoir were examined. in this study, 130 crossbred cows and heifers that have failed to conceive after three or more services were identified, submitted to a clinical examination and blood collection for karyotyping and sent to an abattoir. postmortem examinations included macroscopic evaluation of the genital tracts, bacteriology and histopathology of the uterus. uterine alterations were predominant followed by oviduct and ovarian pathologies. histopathological examination was more sensitive as a diagnostic tool than clinical examination. repeat breeder cows had a predominance of uterine abnormalities (95%), such as inflammatory (42.9%) and degenerative (59.7%) conditions. oviduct abnormalities were found in 29.8 % of animals. furthermore, 1 out 10 karyotyped cows showed aneuploidy. thus, this study stressed the importance of laboratory exams in the diagnosis of the causes of infertility of repeat breeder cows.

Abstract: Objective: To compare clinical outcomes between two first-generation endometrial ablation techniques. Design: Prospective comparative coorte. Setting: Tertiary public hospital, university teaching center. Seventy-three patients with abnormal uterine bleeding unresponsive to clinical treatment submitted to endometrial ablation from October 2011 to September 2013. Methods and Main Outcome Measures: Patients were assigned to either monopolar U-shaped electrode resection with rollerball electrocoagulation (group A, n = 36) or rollerball electrocoagulation alone (group B, n = 37). Mean follow-up length was 359 (280 - 751) and 370 days (305 - 766) in groups A and B, respectively. Bleeding pattern, associated symptoms, failure/success rates were assessed 30, 90, 180 and 360 days post-procedure. Findings: Patient characteristics were similar in both groups (P ≥ 0.05). Surgery duration (mean of 48.5 [±12.0] vs. 31.9 [±5.6] min, P < 0.001) and medium distention use (5.700 mL vs. 3.500 mL, P < 0.01) were decreased in group B. Post-ablation clinical improvement was considerable in both groups. Vaginal discharge incidence after the procedure was lower in group B (30.5% vs. 8.1%, P < 0.05). Hysterectomy rate was 9.6%. Overall success rate was 86.1% and 88.1% in groups A and B, respectively. Conclusions: Endometrial ablation using rollerball electrocoagulation alone may be considered safer than resection with rollerball electrocoagulation, which requires shorter surgical time and less distention medium, and is associated with lower postoperative vaginal discharge incidence. Success rate did not statistically differ between groups, but study parameters in absolute values and percents were superior in group B.
Fourier and Wavelet Spectral Analysis of EMG Signals in 1-km Cycling Time-Trial  [PDF]

Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.513181
Abstract: Frequency domain analyses in electromyographic (EMG) signals are frequently applied to assess muscle fatigue and similar variables. Moreover, Fourier-based approaches are typically used for investigating these procedures. Nonetheless, Fourier analysis assumes the signal as stationary which is unlikely during dynamic contractions. As an alternative method, wavelet-based treatments do not assume this pattern and may be considered as more appropriate for joint time-frequency domain analysis. Based on the previous statements, the purpose of the present study was to compare the application of Short-Time Fourier Transform (STFT) and Continuous Wavelet Transform (CWT) to assess muscle fatigue in dynamic exercise of a 1-km of cycling (time-trial condition). The results of this study indicated that CWT and STFT analyses have provided similar fatigue estimates (slope) (p> 0.05). However, CWT application represents lesser dispersion (p< 0.05) for vastus medialis (189.9 ± 82.1 for STFT vs 148.6 ± 60.2 for CWT) and vastus lateralis (151.6 ± 49.6 for STFT vs 103.5 ± 27.9 for CWT). In conclusion, despite the EMG signal did not change (p> 0.05) according to different methods, it is important to note that these responses seem to show greater values for CWT compared to STFT for 2 superficial muscles. Thereby, we are capable of considering CWT as a reliable and useful method to take into consideration when non-stationary or oscillating exercise models are evaluated.
