[Ab] Resumo:Early detection of power transformer fault is important because it can reduce the maintenance cost of the transformer and it can ensure continuous electricity supply in power systems. Dissolved Gas Analysis (DGA) technique is commonly used to identify oil-filled power transformer fault type but utilisation of artificial intelligence method with optimisation methods has shown convincing results. In this work, a hybrid support vector machine (SVM) with modified evolutionary particle swarm optimisation (EPSO) algorithm was proposed to determine the transformer fault type. The superiority of the modified PSO technique with SVM was evaluated by comparing the results with the actual fault diagnosis, unoptimised SVM and previous reported works. Data reduction was also applied using stepwise regression prior to the training process of SVM to reduce the training time. It was found that the proposed hybrid SVM-Modified EPSO (MEPSO)-Time Varying Acceleration Coefficient (TVAC) technique results in the highest correct identification percentage of faults in a power transformer compared to other PSO algorithms. Thus, the proposed technique can be one of the potential solutions to identify the transformer fault type based on DGA data on site.

[Ti] Título:Discriminatory performance of positive urine hemoglobin for detection of significant hemolysis in patients with continuous-flow left ventricular assist devices.
[So] Source:J Heart Lung Transplant;36(1):59-63, 2017 Jan.

[La] Idioma:eng
[Ab] Resumo:BACKGROUND: Serum lactate dehydrogenase (LDH) is the standard measure for detection of hemolysis and thus surveillance for device thrombosis in patients on continuous-flow left ventricular assist device (CF-LVAD) support. Significant hemolysis has been defined as LDH ≥600 IU/L. However, LDH testing requires phlebotomy, precluding frequent home monitoring. Simple dipstick urinalysis (UA) for urine hemoglobin (U-Hb) overcomes this limitation. This study correlated U-Hb and LDH levels and evaluated the performance of UA for detection of significant hemolysis in patients with CF-LVADs. METHODS: U-Hb and LDH were measured concurrently 956 times in 221 patients with CF-LVADs. Statistics were computed to determine accuracy of UA in detecting LDH ≥600 IU/L, with a positive result being any detected U-Hb. All analyses were performed with and without excluding for 1) conditions associated with tissue damage, which are known to increase LDH, and 2) suspected or confirmed urinary tract infections or hematuria, which are known to cause hemoglobinuria for reasons other than hemolysis. RESULTS: Mean LDH for absent/mild/severe U-Hb was 360 IU/L/467 IU/L IU/L/777 IU/L without exclusions, 354 IU/L/444 IU/L IU/L/651 IU/L after excluding non-hemolytic LDH elevations, 370 IU/L/513 IU/L IU/L/1,357 IU/L after excluding urinary tract infections and hematuria, and 367 IU/L/470 IU/L IU/L/1,217 IU/L when both exclusions applied (all p < 0.001). Absent U-Hb had a negative predictive value for LDH ≥600 IU/L of >90% for all analyses. CONCLUSIONS: Serum LDH is significantly associated with U-Hb levels. Absence of U-Hb appears to efficiently exclude significant hemolysis in patients with CF-LVADs. Because it can be performed by patients at home, hemoglobinuria monitoring may enable more intense surveillance and earlier diagnosis of device thrombosis.

[Ab] Resumo:Failure detectors are one of the fundamental components for maintaining the high availability of vehicular cloud computing. In vehicular cloud computing, lots of RSUs are deployed along the road to improve the connectivity. Many of them are equipped with solar battery due to the unavailability or excess expense of wired electrical power. So it is important to reduce the battery consumption of RSU. However, the existing failure detection algorithms are not designed to save battery consumption RSU. To solve this problem, a new energy-efficient failure detector 2E-FD has been proposed specifically for vehicular cloud computing. 2E-FD does not only provide acceptable failure detection service, but also saves the battery consumption of RSU. Through the comparative experiments, the results show that our failure detector has better performance in terms of speed, accuracy and battery consumption.

[Ab] Resumo:STUDY OBJECTIVE: To determine an effective method of intrauterine device (IUD) retrieval from pregnant women who had previous unsuccessful ultrasound-guided IUD extraction failure. DESIGN: A retrospective cohort study (Canadian task force classification II-1). SETTING: A gynecology department of an outpatient clinic. PATIENTS: Pregnant patients in their first trimester with IUD in situ who underwent prior unsuccessful ultrasound-guided IUD extraction. INTERVENTIONS: Hysteroscopic IUD extraction guided by transabdominal ultrasound. MEASUREMENTS AND MAIN RESULTS: Between 2011 and 2014, 7 of 8 pregnant patients who had undergone previous failed attempts at IUD retrieval via ultrasound guidance underwent successful removal via ultrasound-guided hysteroscopy performed without anesthesia. The sole patient with extraction failure was in her 12th week of pregnancy, and the procedure was concluded to avoid risk to the fetus. Minimal vaginal bleeding was experienced by 2 patients after the procedure. Seven of 8 patients delivered at term without any obstetric complications. One patient had a miscarriage in her 8th week of pregnancy, 2 weeks after successful IUD removal. CONCLUSION: A novel, easy outpatient hysteroscopic technique without anesthesia is presented in case of failure of previous ultrasound-guided IUD removal in early pregnancy. Results are encouraging in this difficult context.

[Ab] Resumo:INTRODUCTION: Peripherally inserted central venous catheters (PICC) are widely used in cancer patients and ultrasound-guided PICC insertion could improve success rate. The tip position of the catheter should be located at the border of lower one-third of the superior vena cava (SVC) and cavo-atrial junction. The migration is malposition at the late stage after PICCs were inserted, and catheter malposition was associated with thrombosis and other complications.After patient's informed consent, we report a case of a 66-year-old male with twice catheter migrations resulting in thrombosis after being diagnosed with cardiac cancer. CONCLUSION: The correct position of the catheter tip can ensure the normal use of PICC and reduce the complications. For the migrated catheter, it should be removed as soon as possible, and when thrombosis has been developed, standard anticoagulant therapy should be given.

[Ab] Resumo:BACKGROUND: Patients who have pacemakers or defibrillators are often denied the opportunity to undergo magnetic resonance imaging (MRI) because of safety concerns, unless the devices meet certain criteria specified by the Food and Drug Administration (termed "MRI-conditional" devices). METHODS: We performed a prospective, nonrandomized study to assess the safety of MRI at a magnetic field strength of 1.5 Tesla in 1509 patients who had a pacemaker (58%) or an implantable cardioverter-defibrillator (42%) that was not considered to be MRI-conditional (termed a "legacy" device). Overall, the patients underwent 2103 thoracic and nonthoracic MRI examinations that were deemed to be clinically necessary. The pacing mode was changed to asynchronous mode for pacing-dependent patients and to demand mode for other patients. Tachyarrhythmia functions were disabled. Outcome assessments included adverse events and changes in the variables that indicate lead and generator function and interaction with surrounding tissue (device parameters). RESULTS: No long-term clinically significant adverse events were reported. In nine MRI examinations (0.4%; 95% confidence interval, 0.2 to 0.7), the patient's device reset to a backup mode. The reset was transient in eight of the nine examinations. In one case, a pacemaker with less than 1 month left of battery life reset to ventricular inhibited pacing and could not be reprogrammed; the device was subsequently replaced. The most common notable change in device parameters (>50% change from baseline) immediately after MRI was a decrease in P-wave amplitude, which occurred in 1% of the patients. At long-term follow-up (results of which were available for 63% of the patients), the most common notable changes from baseline were decreases in P-wave amplitude (in 4% of the patients), increases in atrial capture threshold (4%), increases in right ventricular capture threshold (4%), and increases in left ventricular capture threshold (3%). The observed changes in lead parameters were not clinically significant and did not require device revision or reprogramming. CONCLUSIONS: We evaluated the safety of MRI, performed with the use of a prespecified safety protocol, in 1509 patients who had a legacy pacemaker or a legacy implantable cardioverter-defibrillator system. No long-term clinically significant adverse events were reported. (Funded by Johns Hopkins University and the National Institutes of Health; ClinicalTrials.gov number, NCT01130896 .).

[Ab] Resumo:RATIONALE: Various factors can cause ventilatory failure after endotracheal tube (ETT) intubation, which is associated with increased patient morbidity and mortality. PATIENT CONCERNS: A 76-year-old woman who was diagnosed with a hemopericardium and suspicion of a major-vessel injury due to dislocation of the clavicular fracture fixation screw. DIAGNOSIS: Non-resterilized reinforced ETT obstruction caused by a structural defect. INTERVENTION: Endotracheal tube was exchanged. OUTCOMES: The ventilator profile showed rapid improvement. LESSONS: Anesthesiologists should consider that a non-resterilized reinforced ETT may be defective. An ETT defect can cause high PIP and ETT obstruction without kinking or foreign materials.

[Ab] Resumo:Endoscopic bilateral stenting has been increasingly performed for advanced hilar obstruction. As disease progresses, stent malfunction eventually occurs. However, endoscopic reintervention is difficult in these patients. We aimed to evaluate a suitable reintervention procedure for stent malfunction after stent-in-stent (SIS) deployment for malignant hilar obstruction.Among 52 patients with bilateral stenting performed using the SIS method between September 2009 and June 2016, 20 patients with stent malfunction were enrolled in this study. Reintervention was performed endoscopically or percutaneously. Technical and functional success rates were evaluated retrospectively.Technical and functional success rates of endoscopic reintervention were 83% (10/12) and 80% (8/10), respectively. Endoscopic bilateral and unilateral reintervention success rates were 75% (6/8) and 100% (4/4), respectively. For bilateral reintervention, either plastic or plastic and metal stents were used.Endoscopic reintervention could be considered for in-stent malfunction if patients are in fair condition after SIS placement for malignant hilar obstruction. Decisions regarding whether to use bilateral or unilateral drainage and the type of stent to use should depend on the conditions of the disease and the patient.

[Ab] Resumo:According to current best knowledge, an MRI scan can be performed for patients with cochlear implants. The warnings and recommendations of the implant manufacturers must be followed strictly to prevent complications, such as overheating, migration or demagnetization of the magnet in the implant. We report on a case of cochlear implant magnet dislocation as a complication for an MRI scan. The patient had a tight bandage around the head to hold the magnet in place as recommended by the manufacturer, but apparently the bandage was not in the correct place.
